Several have mentioned this potential fix. I'd do this. Should take care of the flashing "D".

Next I'd dump the current mix in the transmission and be doing a bunch of drain and fills with Honda DW-1. I wouldn't use any more additives or non-OEM fluids in the transmission.

The correct fresh ATF may fix the shudder.

Flashing D light means that the computer has stored a code, which you should investigate before buying any more stuff.

Agreed with dumping all in the tranny now & going with Honda DW-1 paired with Lube Guard Red. Of course, posters mentioned about fixing the sensors also. My Acura has strictly Honda DW-1 & Lube Guard Red, likes/luvs that combo.

So I got a response from the manufacturer for my question:

"Due to heat you will loose the lighter ends of Sea Foam and some volume but the cleaning oil that will dissolve and prevent varnish formation as the fluid ages will remain in the fluid many miles"

I personally think Seafoam's line of products are overpriced, they are always 2x to 2.5x more expensive than Berryman's B-12 Chemtool. They both probably have less than $0.35 worth of raw materials inside their little cans. Their marketing in the additive industry to maintain such high prices and volume is nothing short of impressive, worth to teach in business school assimilate

OK, so why do you go on and on about an additive (first positive and now negative) and refuse to address the probable mechanical issue that has been pointed out to you by 3 forum members?

This seems to be a common thing with new low-post forum members.

The transmission was toast 214K miles.

Replacing the sensors is about as hard as an easy spark plug replacement.


I know... those sensors and solenoids are cheap and externally mounted too! I'll get them replaced before this spring.

Also I've ordered the external inline filter from WIX:
https://www.wixfilters.com/Lookup/PartDetails.aspx?Part=1871906

The filter just takes a 24mm open ended wrench and two 10mm bolts to undo, after taking the air intake hose, battery tray, and maybe also the plastic engine cover off to access it...

Left sample was collected from a drain & fill after around 350 miles after the 16 oz of Sea Foam Trans Tune was added, it's dark and opaque and has the strong smell of isopropanol!

Right sample was collected from another drain & fill after around 375 miles to slowly remove all the SF TT. Less isopropanol smell to it.

After each subsequent drain & fill, the magnetic drain plug was cleaner and cleaner...

I will do two more drain & fills spaced out. I haven't been driving the vehicle much... No flare ups nor shudder to report, but I've experienced only one single hard 1-2 shift during this entire interval.

Sea Foam Trans Tune is doing its thing, its safe duh, no leaks... its updated 09/11/2019 SDS:
hyrdocarbon blend < 95% (most likely pale oil & naptha blend)
isopropanol 67-63-0 < 25%

I'm thinking K&W Trans-X is similar, but with stop leak chemicals...
I was also looking at K&W Trans-X SDS out of curiosity:
64742-52-5 distillates (petroleum), hydrotreated heavy naphthenic 76.2543%
67-63-0 isopropyl alcohol 10 - 20%
1330-20-7 xylene 5 - 10%
108-88-3 toluene 3 - 5%
123-42-24-hydroxy-4-methylpentan-2-one (diacetone alcohol) 1 - 3%
100-41-4 ethylbenzene 1 - 3%

All seafoam products are chemically the same. Just different labels and marketing. The transmission got a drink of pale oil, naphtha, and isopropanol. I would dump that ASAP. Isopropanol does not belong in the transmission.

absolutely, I'm planning to do at least two more drain & fills and maybe a third one for good measure spaced out...

anyways the pictures posted doesn't tell the whole story from both a lighting standpoint and also the old fluid had been sitting/settling contaminants.

the first drain & fill after initial treatment was definitely much more dirtier than the pictures show... as expected and going to plan smirk

Hi ,I have never used Seafoam. Questions are How much Seafoam to add to a sometimes "groaning " p/s on a non leaking '03 Dodge Caravan ? How about a 1960's Mopar 727 that "sometimes" has a harsh 2nd. to 3rd. shift ? (about 9 qts. capacity) any thoughts ? Thanks and Happy Holidays Everyone !

For all the time and money you've spent on additives and ATF you could have fixed the real problem.

None. Seafoam does not belong in anything. Let it stay on the shelf at the parts store where it can hang out with its friends Lucas and Slick(50).

Honda/Acura models equipped with a four- or five-speed automatic transmission may overheat the converter. Insufficient flow to the TCC release circuit at low RPM allows the lockup piston to drag on the cover, generating heat. This heat glazes the TCC lining and overheats the fluid. Eventually the slip rate cannot be controlled due to lining failure, resulting in code P0740. To prevent this problem, Sonnax offers a drop-in converter charge regulated pressure regulator valve 98892-04K. This valve allows more flow to the converter and cooler circuits, increasing converter charge during low pump output conditions, and includes an internal checkball to prevent converter drain back when the vehicle is off. The same valve design will assist converter charge and TCC apply pressure during low-output/high-load demand situations.

I dont have an OBD-ii scanner but, I'll try one of the big box auto parts stores to see if they can pull a transmission module code, I know higher end scanners can do that...
