So if you have read my other post, you know that I blew up the transmission in my LX yesterday.
I went and picked up a transmission today.



Its out of a 2008 CVPI. Supposedly has only 1k miles on it, and with the condition its in Im tempted to believe that. Or its close enough I dont care. I paid $840 for that beauty.
Because its from an '08 its not a drop in, namely the EPC solenoid has different operational characteristics than the -04 part, so I have to change that. Ill just get a new one.
Since its from a Police car it has a 11.25" torque convertor and extended tailshaft housing. So, Ill have to change my flexplate out for one with the smaller bolt pattern. I already have a short police aluminium driveshaft to go with the extended housing, but I have a standard yoke on it, so Ill have to get a u-joint and put the Police yoke back on it to match.
The trans also has a TSS (Turbine Shaft Speed) Sensor that I dont need; Ill just leave it installed and disconnected. Because of that it also has a titanium sun shell which would allow the TSS to read input shaft speed through it. :P
The advantages of the later trans include a stronger gearset, upgraded intermediate mechanical diode, and improved OD band.
Also, looks like they broke the bulkhead connector so Ill have to scavenge that out of my old trans.

Thats where Im at right now. I have to gather the additional parts needed. I also need to either acquire a new transmission cooler, or find a place that has a heated flushing machine to clean it out.
Since Im going to be installing 4.10s in the rear sometime after this debacle, I am going to do the forced tailshaft lube modification to this and I will also JMod it as SOP before it is installed.

I will update this thread as progress is made.

Cool. Kind of sad to hear the trans went out, seems they last well for most. Heavy foot issues? Just kidding, trying to lighten the mood a bit.

Good luck with the swap, that seems like a terrific deal on the used unit...

Yeah, I have some ideas on why it went out. I will be dissecting the old one before the new one goes in so I can find out why it went out and try to prevent that from occurring again, espically if it was something I did to it.

Maybe you should just cut your losses and give the car to me? wink

Love the crown vics. The police transmission is a 4R75 right?

I'd absolutely love to get a civilian Vic, JMOD it and do a 3.55 or 3.73 rear end. I would think 4.10 would hurt highway mileage a bit much for me. I know the modular v8s like to wind up, though.

I can soooooooooo close to making an offer on this Saturday. Ultimately I didn't because it had heated power seats, electronic climate control.

You wouldn't want mine, because it has EATC as well.
If you are gonna put gears in it, you will need a tune, and if you need a tune you might as well get the Police Airbox and ziptube. Worth 11HP. Since its OE stuff it fits just like the original but you would need the tune to correct the MAF tables.

Yes, its a 4R75E. I was thinking about 3.73s but really once you get up that high, might as well go for the 4.10s.

I generally drive like a granny. Just 2.73 gear ratios make me cringe. As handy as it is to go 60 in 1st gear and not hit redline, or idle down the highway, we have too many hills.

I think at that point, it would actually hurt economy. Good for EPA ratings, I guess.

Do you expect much of a FE hit? Seems like it would be cruising > 2000 when on the highway?

It would run about 2800RPM at 75MPH. Thats about 1000RPM more than it does now with 2.73s. As it is I get 25MPG at 75MPH with cruise control. I guesstimate a 10% drop. Mostly it will be increased frictional losses from the engine and transmission spinning at the higher RPM.

Since the previous transmission failed, I would definitely get a new transmission cooler. Its not worth the risk and stacked plate coolers aren't that expensive.

Got any pics of this car? I've always loved the Vics.

Surprising that it blew at such low mileage. Usually they last forever in the crown victorias.

Do you think the failure is related to your recent installation of that deep aftermarket pan?

I agree, that thing will rock with 4.10s. It'll be a lot of fun.

So, I went out and did some testing on the bad trans this morning. Trying different things to see exactly what is going on. I have a hypothesis but I dont really want to post it in case Im wrong. I built it from research on the intertubes and my recent testing seems to be bolstering it..
I will post it anyways because Im trying to get over my fear of being wrong.

So, before when I drove it home, I only had (shuddering at takeoff) 1st and 2nd. 3rd and 4th never happened, it would just stay in 2nd all the way out. This confused me because if it was actually trying to engage OD with no OD band I would end up in neutral since it opens the Forward clutch.
The shift pattern is:
D (1st) Forward clutch on
D (2nd) Intermediate clutch on
D (3rd) Direct clutch on
D (4th) Forward clutch off and OD band on
M (2nd) Forward, Intermediate, and OD Band on (the OD band comes on in manual second to allow for engine braking, 2nd in (D) will just return to near idle)
M (1st) Forward, and Reverse band on (Reverse band on for same reason as OD band in Manual second)
I had checked the fluid and it was within the okay range.

Today I went out and dumped fluid in it until it was overfull.
Partial success. First thing I tried was getting it up to about 20mph, put it in manual 2nd and let off the throttle. The engine returned to idle. So the OD band is shot. That I expected.
Then I took it up to 50mph. Somewhere in there it attempted 3rd. I felt an ever so slight bump, but it again never completed. Better than it was before; it never tried. Once I crossed the OD threshold, it went into neutral. So it tried to go into OD and opened the Forward clutch unlike before I had overfilled it.
Ever since I had installed the trans pan, I have had problems getting the fluid level right. I usually ended up with the level right at or just above the max mark with the trans hot. It seemed like if I set it in the middle of the range, it would be too low when cold.
Recently I changed the Racor filter I have on the cooler line. I recovered what fluid I could, but I still lost about a half a quart. Shouldn't be enough to affect it since I was right at the limit at the start, right?
Well, maybe.
See the cast pan I have has these towers in the middle of the pan that stick up and are supposed to hold the filter up to the transmission. I recently came across I post on the marauder forum of someone who smoked direct and OD (sound familiar?) in his fresh transmission after the aftermarket cast pan he had let the filter fall out of the transmission valve body. He used playdoh and found a pretty large gap between the towers in the pan and the filter.
I dont think its actually fallen out completely; what I think what has happened is that it has dropped out enough to become unsealed and the pump is sucking air at that interface. When I was nearly overfull the problem was mitigated by the fact that point was probably still under fluid most of the time. After I changed the filter and brought the level down to normal it could no longer operate correctly.
I killed it trying to do a WOT 2-3. If you see my shift tables above, you'll note that at that point it has to keep 2 clutches locked and bring on a third. At WOT the pressure commanded is quite high. More pressure = more fluid needed. It ran out of fluid; couldn't build the needed pressure. Boom.
I really really REALLY want to start tearing it apart, but its just too [censored] cold. Im outside a lot at work as it is and I just want to stay inside on the weekends.


Oh! I almost forgot. I got the correct flexplate from a crownvic forum member. I drove it out to me and didnt even charge me for it!

Some parts arrived this week.

Im surprised at all the US parts I got.
New Dayco tensioner because the old one is annoying me. New pair of NTK O2 sensors (seem like theyll be easy to replace with the cats and trans out of the way). Nice Spicer sealed U-joint to put the CVPI yoke back on the aluminum driveshaft and a pair of output shaft seals.
I was supposed to have more, but weather has delayed some of it.
I have Monday and Tuesday off, so I plan to get it up and start disassembly this weekend.

If the gearing upgrade is part of this swap I would take the driveshaft to the shop for rebalancing and new u-joints.

It's going to be spinning a LOT faster...

No, unfortunately I had to use the cash for the gear swap on the trans. That's how I was able to pick it up the day after I blew this one, you see.
This aluminum shaft is good to 115 with 3.55s (factory speed limiter in CVPIs). So thats 5300rpm. Reversing it back out and correcting for my slightly larger tires it looks like the limit is 100mph on the dot.
I'd like to find a Alcoa AMMC (Aluminum metal matrix composite) out of a MY2000 CVPI. They had 130 limiter with 3.55s. Looks pretty close to 6000rpm. Little bit better at 114mph.
The AMMC shafts are hard to find, being one year only. I'll probably end up buying a Dynotech driveshaft. They have both aluminium and carbon fiber driveshafts available for the Crown Vic. Ill probably buy whichever will be okay to 7000. Thats 133; more than enough.

Good, just glad you are aware of the stresses by shorter gears.

Lots of folks find out after they destroy the floor pan after failure!!!

My sympathies on the cash thing, this sort of stuff never happens when you're ready for it...

Yup, I seen pictures where someone put 4.10s in a CV and left the civilian steel shaft in.
I think he was going 95mph and the transmission tailshaft housing exploded. Caused a lot of damage underneath as the thing flopped about until he got it stopped.
Course, the trans was gone too. Not only was the tail housing gone the casing itself was cracked.
Thinking about it, itll probably be worth it to invest in a driveshaft loop. Metco makes one for these cars.

I grenaded a stock Mustang yoke and it blew the tailstock off the transmission. I was probably only doing about 80(km/h) but holy *bleep* did that make a lot of bad noises banging around on top of the H-pipe crzy It marked up the tunnel quite badly.

CVPI shaft with Civi Yoke next to CVPI yoke (longer). I put the standard yoke on the CVPI shaft in order to make it compatible with the standard transmission. I had to use a custom conversion joint. I originally ordered a u-joint for a 2004 CV. But, it was too small for the CVPI shaft. So, I ordered a 1330/1350 conversion joint. That didnt work either because the 1330 caps were too small for the standard yoke. That was a headscratcher. Some sort of custom Ford size. But, I found that the actual bearing diameter of the Ford caps (1340?1335?) was the same as a 1330. So, I took two caps from the first joint I bought and put them on the conversion joint.
Bam, custom conversion.
All that work, and now it has to come back off. Ah, well. Itll be better this way with a nice Spicer sealed joint rather than that Moog junk.
Back on track, I pulled the pan. Well, first, I pulled the drain plug.

Lots of metal flecks. As many as it can hold, anyway. I dropped the pan, and the filter is still firmly attached to the VB, so that eliminates that possibility. Ill have to go deeper to find out why it failed. Oh, yeah, I didnt get a pic, but lots more flecks floating in the bottom of the pan. I put it back on so I have a place to jack from. The manufacturer says thats okay as long as a piece of wood is used underneath.

New tool time.

Had trouble getting the nuts off that hold the cats to the exhaust manifold. Finally just went and got an impact driver. I bought it as I am familiar with them; I use them at work all the time. I wanted one with a 3/8" drive and not the 1/4" drive with an adapter, but this was all they had. Its the same gun, but my experience is the 1/4" drive fatigues and eventually explodes. But that's in an industrial setting; constant use. Hopefully Ill get a few years out of it before that happens.
So now I have these out, thanks to it.

So, um, after you somehow got the cats unbolted from the manifolds using a cordless electric screwdriver did you then buy a lottery ticket? If not, it might be a good idea to go do that now.

lol, its an impact. Mighty handy and more powerful than you would think. Like 133ft/lbs. I said that the 1/4 drive end on it tends to explode eventually. I wasnt kidding. I use them at work all the time and deal with the aftermath of untrained children (adults) that think giving it full gas on a 3/8" bolt is OK.
Anyway, so Im currently at a stop because the crossmember is giving me trouble. Yeah, Im that far. Its the only thing keeping me from pulling it. The fit on the 03+ Panthers is REALLY tight. I think the pockets on the frame that it sits in are way undersized and they just force it in there when it is built. what makes it worse is there really isnt anyplace to leverage off of that is sturdy enough. Ive got my crowbarr out, but it isnt really helping. Got my mallet too, but its not helping much because theres no room above to get a swing on it. Ive dropped it about 1/2" on one side and about 1/4" on the other.

Yup, I seen pictures where someone put 4.10s in a CV and left the civilian steel shaft in.

Course, the trans was gone too. Not only was the tail housing gone the casing itself was cracked.
Thinking about it, itll probably be worth it to invest in a driveshaft loop. Metco makes one for these cars.


I grenaded a stock Mustang yoke and it blew the tailstock off the transmission. I was probably only doing about 80(km/h) but holy *bleep* did that make a lot of bad noises banging around on top of the H-pipe crzy It marked up the tunnel quite badly.


Mine came right through the floorboard in a 63 cadillac! Ripped the back seat to shreds and would have been a REAL problem for anyone back there!

Driveshaft loops are amazing things haha.

The amount of damage a drive shaft can do is downright scary. I've seen a fair share of it from a few different friends who followed the classic style of big engine, leave everything else stock. Lets just say i'm glad I wasn't in back.

Same with trans... Some can become a bomb when pushed outside their limits.

That reminds me of a rather crazy one I saw: The flywheel on a Camaro come off at the strip at WOT and fly out the cowl in pieces. It cut through a chunk of the trans tunnel and was extremely close to removing the driver's gas pedal foot from what I learned later.

If its one thing that will catastrophically destroy a drivetrain its the strip haha. The worst i ever experienced was in our superbee. 4100 lb car, built 440 on a 150 shot, and a mildly built 727. Let off the transbrake at launch and grenaded the front drum inside of it.

Thankfully it was only a temporary transmission while the th400 was being rebuilt and we had a scatter shield/diaper under it. It completely blew the center out and ripped the shield right off. The tail was still hanging from the rear mount and the bell housing was still bolted to the block...just nothing in between. Without that shield I cant imagine the things that would have came through the floor pan.

Liz lost the driveshaft on her Grand National a while back. Note: some u-joints do not like wrinkle-wall slicks, 3900lb cars, and 800+HP! No major carnage (didn't even take out the trans!), but the last foot of the drive shaft took on this interesting "S" shape...

The car now uses non-greaseable (read: not drilled for grease passages) Spicers. And yes, it DOES have a scattershield!

Went and bought some Schaeffers #204SAT from a local distributor.

I love this stuff. Cost me a pretty penny. Im probably going to use a whole case just to get it running. Then I have to also refill the power steering since it shares the cooler with the transmission. That's a couple quarts. Need some for top-up from changing the Racor filter. I think Ill probably have about 6 quarts left all said and done.
Also did this.

Yeah, I painted the flexplate. Yeah, Im a dork. No Im not trying to avoid going under it and actually working on it. Stop looking at me like that.

So, I got tired of not making any progress.
I bought three prybars trying to find one that would help me remove the transmission crossmember.
I finally had enough when I had a 3ft prybar stuck in the crossmemeber, and Im standing up, jumping on the thing and its not moving at all.
All I had managed to do was bend the crossmember and the frame mounts.
It'd probably be different if I had a car lift and could work under it, but with the limited clearance it really hindered getting a swing with a hammer and how the prybar could be positioned. Really limited stuff to get leverage off of besides the floor pan.
So I bought this stuff:

I started off trying to cut it through a thin spot to let me leverage one side out, then the other.
Then I got the idea to just make a relief cut in the top of it on one side. That worked beautifully. I had to make a large cut in the bottom to get my small 4 1/2" grinder in there, but once I did that and made the cut it slid out with relative ease. Then I wiggled it up and down, hammered, wiggled it some more; eventually worked it out of the other frame pocket.

I have another crossmember I bought off ebay on the way. This one is scrap.
Trans should be out here soon.

I know I can attract some views with some...
DESTRUCTION PHOTOS!

First bad thing that came tumbling out was the large stub shaft piece. Everything before that was good, even the [censored] OD band was prestine.

Once I got the direct clutch out, I had to hammer the small piece out of it.

Yeah, thats scrap.

Also scrap.

Clutches were a bit wierd. The first three (coming in from the front of the trans), were good to near mint. Then the forth one was tore up on one side a bit and wiped clean on the other. The rest following were also wiped clean.

So, I talked with someone knowledgeable in these transmissions and the bushings getting torn up and seizing on the sun gear and planetary are fairly common.
What is uncommon is the stub shaft breaking at my power level. Its a known weak point, but really only affects modified cars 400RWHP+
Not really 220RWHP (On a good day) lightly modded vehicles.
We discussed the probability of it being the tune. He said there have been complaints coming in lately about shift issues with the person I had do my tune.
I told him I had put a wideband on the car and found the tune was giving me a WOT AFR of ~14:1 which is [censored] lean. Surprised I havent melted the cats. Good thing its N/A or I would've surely melted a piston.
That has nothing to do with the trans; but it makes you wonder how the rest of the tune is.
Before I bring it back into service Im getting the SCT Pro Racer software and Ill build my own tune which is the purpose I bought a wideband for anyway.

Minor update:
First, More parts:


For doing the VB modification on the new trans. Im going to do that this weekend and have it ready for install next weekend. My new crossmember will not be here until Monday, so I can't install it anyway.

Got a O2 bung welded into the driver side cat for my wideband sensor. I had pre-marked the location prior to removing it from the car. I picked a location with a fair amount of flexibility so the location didnt have to be machinist precise to make it fit. It was $30 to have it done off the car like this.

New flexplate installed. This is a later 'dual pattern' flex plate that can accept either the 12" 'standard' or 11.25" 'performance' torque converter.

Anybody good with looking at broken parts and seeing what happened?
The large stub shaft piece was pretty much a melded mess, since it kept spinning. In one spot on the broken end it was blue from the heat generated.
But the small piece is mostly intact from its original state after the breakage occurred. It just got pushed into the hub and only got wiped on the high spot.
I got curious after seeing the ADTR.net 'RocketCouch' 600RWHP 1992 Crown Victoria shear the same part. But it was a clean shear right at the top of the splines. Like someone just spun it while holding against a blade and cut through it.
Mine is a bit different.

I think mine somehow ended up cracked which weakened it enough to allow my comparatively weak engine tear it apart.
I circled in blue a large area I think was cracked before the final failure. About the last 2mm towards the outside of the shaft is broke like this all the way around. Smooth, sharp edges.
In red I lined a crack I found. It starts (I don't really know where it started, that is just where it is convenient for me to start) about 3 splines across from where it breaches the surface in a valley. It goes across one spline at an angle then makes a almost u-turn to head back in the valley. About .5mm under the valley it makes a 90* turn and goes directly under that spline.
In green I think is where it finally tore off on that last 2-3.

But, this is all just my guessing.

Opened the new transmission to modify the valve body and swap the EPC (Electronic Pressure Control) Solenoid.

The correct one for my 2004 is on the left and the incorrect one used 2005-2008 is on the right. The new one will not give the correct pressure commanded by the PCM and will quickly burn up the trans. The manual shift lever had to be mostly removed in order to replace this.

These are holes I enlarged and the drill bits used.
Hole #2 (Intermediate clutch feed): 7/64
Hole #4 & #5 (Direct clutch feed): 7/64
Hole #6 (Direct clutch exhaust): #21 drill
Hole #7 (Reverse servo feed for Manual 1st): 3/32
Hole #10 (Reverse feed): 3/32"
Hole #9 & #11 (Forward clutch feed): #31 drill

Back together with my modified 'Supertuff' plate.

Ready for install. Its not 100% complete, I didnt put a filter in it. Also, the transmission pan that it has is scrap from it sitting on it like this. I have the infamous 'Uhaul' factory pan with drain plug, on the way to replace this one.

So last night I pulled the radiator so I could replace the transmission oil cooler.



Giving me acres of room in there. I took the time to install the new tensioner I bought when I first started this.

This morning, after work, I decided to move the A/C accumulator forward on the frame, drilling new holes for it.

The purpose of which is to accommodate the Mustang GT belt routing.

I overlaid the difference. On Crown Vics, the pulley just to the left of the alternator is a ribbed one, and the belt runs over it, then drops down around the A/C.
On the Mustang, the same pulley is a smooth one, so the belt runs under it, then over a ribbed pulley before going around the A/C.
I had had my car setup like this, but, when I fixed my A/C I had to swap back to factory because of the low pressure sensor sticking off to the side there.
The factory 03-04 accumulator had the sensor standing straight up off the top, then in 2005 Ford changed it to the design seen here. If you order a service accumulator, you get the new design.
Several other people have run into the problem and fixed it by doing what I did here, move the accumulator forward 3/4".
Difference is, it was really easy for me to perform with no radiator and fan in the way. laugh
Then Ill just zip tie the harness to make sure it does not get sucked into the belt.

I'll second that. extremely impressed. I agree with your thoughts on the stub shaft metal fatigue failure. cracked first then saw fatigue on the inner portion of the shaft. I'm not a mech-E., though, so I could also be wrong.

Im glad you guys like my work!
I have bad news.
Im not going to make putting the trans in this weekend.
I did something to the VB that I'm having second thoughts about and its irritating me. I thought about it all day at work today and got myself worked up about it; so, I'm just not going to let it fly like I thought I was.
I will get the radiator back in; that isnt too hard.
Also, I got another improvement in the works.

So, on the 03-04 Panthers, the lower dash insulation (arrow) does this. It droops down and lays on the light-off catalyst.

Yeeeeah. You can see where it had been rubbing on the cat. According to the TSB for this, it can cause "Charring, smoke, and fire."
Lovely.
Ford will fix it for free...ooooh, wait. It isn't a cop car or a taxi so it does not apply.
Unfortunately, Ford excluded Civi Panthers from the TSB because it only is a problem with the "unique drive cycles of those vehicles." Or some shishka like that.
I think I probably use the car at least as hard as either of those, so Im going to perform the TSB fix myself. Its stupid simple.
All that has to be done is cut the insulation along the transmission tunnel, and rip the side pieces out of the frame. Leaving only the section above the trans in place.
Then these pads are stuck onto the firewall above the cat.

I got the part number off the TSB and bought them online. It was $40 for a pack of two pads. If anybody decides to do the same thing, order a quantity of two. In the Ford system the MSRP is per pad, but it comes in a sealed package of two so you have to actually order two.
I have to place the pads right above the cat, so I will wait to install until I have the cats back in place. Watch for these to show up again later.

Putted around with it a bit this morning.
Double checked the VB and my fears were unfounded. Im glad I checked, though.
Got the radiator back in and everything hooked up. Refilled with the coolant I drained out of it (I used clean containers) and the power steering got a quart of Schaeffers ATF.

Got the belt back on in the Mustang configuration using a Marauder (93").

Installed a new Racor transmission filter. Figure Ill let it go 5k miles and change it then it should be good for another 30k. These filters are pricey!

In the new parts arena, Ive received my new transmission pan.

The infamous U-Haul factory transmission pan with a drain plug.

Also, I discovered I bent one of the bellhousing bolts. Im still going to try and land the trans tonight or tomorrow. I'll just be short a bolt.

Thanks for the update! You won't likely even know about the bell housing bolt missing, it shouldn't be a problem.

I really like the drain plug equipped pan!

Transmission has been landed.
Had an oops moment when me and brother got it up there and I realized the converter was not fully seated. It was flush against the flexplate but the trans was still 1/2-3/4" away from the engine. Instead of bringing it back down, I had him but a wrench on the engine and spin it. It took just a 1/4 turn and the converter seated allowing the trans to seat at the same time.

Yeah, Im still going to try to get another one. Im not going to stop for it though. I can put it on later.

Got it running! Had some hiccups. Before I ran it, I loaded my first DIY tune onto it.
Ill get into that later.

I didnt have any room to back up my phone, but you can see the new sticky heatshield in-place above the cat. (Also, Wideband O2)

Pouring near $10/quart fluid in. With any luck, Ill actually leave it in long enough to get my money out of it.

This was the first thing I did, was fill it with fresh gas. Second thing was to wash it.
This whole time it was hesitating something fierce and I knew I had to fix my tune, but I wasnt aware of just how bad it was.
It was on the way home that I found out exactly how bad. I went WOT and the Wideband went to 1.3 Lambda. (19:1AFR) I immediately pulled out of the throttle as soon as I noticed this. It didn't seem to have hurt anything, so I babied it home.

Got back home and looked over my tune to find that the MAF table had been reset back to stock rather than the Marauder MAF table I had loaded. I KNOW I loaded it so I must've accidentally reloaded the stock table.

Once I loaded the proper MAF table in and put in on the car, it was perfect. I wnet further and adjusted the Base Fuel Stoichiometric to match E10 fuel. Now its perfect. Im getting .82-.83 Lambda at WOT. Will probably do some adjusting to the MAF table to lean it out a little (Im actually requesting .85 in the fuel tables). But, thats so little difference Im not too worried about it, especially since its on the safe side.

Video time!

Listen to the valvetrain clatter! its been over 3 months since it was running. Probably quite dry up top.
Then the power steering pump finishes emptying the reservoir dry and begins sucking air.
It idles like it has a cam in it because of the wrong MAF table in the tune.

Wanted to give a 1000 mile final update kinda thing.

76,718 to 77,718
No problems to report.
Trans shifts awesome. Of course I have direct access to the tune, so Im doing a lot there, but I don't think it would be nearly as good without the mods I did to the valve body. I tried to get a video of it, but, it was useless. The mic just picked up bass REALLY well and made my exhaust sound significantly louder than it actually is inside to the point you couldnt tell what was going on at all.
But, suffice to say it shifts what I would call drama-free. It doesn't slide, but it doesn't slam either. It just snaps through the gears.
I am so happy with how it all turned out. It sucked blowing money on a new trans, but I got a nearly new transmission with all the factory upgrades and improvements the later cars got. Then I went and upgraded the valve body to improve that as well.

It does seem to run about 10F hotter than the old transmission, but I thought of a couple reasons.
The obvious one is I didn't reinstall my aluminum deep pan. But, IIRC, I never saw that much drop when I first installed it. Its pretty tucked up into the car anyway and I doubt it gets much air.
The converter it came with is the smaller factory 11.25" 'performance' torque converter that stalls 300-400rpm higher than the 12" the car came with. I can tell the difference around town and the slight additional slip may be adding a couple degrees.
I didnt think either of those were full answers though.
However, then I remembered I used the circuit board inside the transmission from the new one. The thermistor is integrated with the circuit board. If the tolerance is +/- 5% for that particular thermistor, which seems reasonable, then the range at that temp is nearly 10F. Ill try swapping to the original board to see if my idea is correct.

Figure, Ill give it another 4000, and Ill change both filters, (the Racor and the pan filter) fresh fluid, and then it should be good for the long haul. Ill swap the circuit board at the same time as Ill have to remove it to re-torque the valve body anyway.
