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?

That pan has been on for 46k miles.

Oh, LOL!

Do you still think it was a contributor though?

possibly. I don't think it's going back on.

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