Petronski,

I recommend a Hayden plate style cooler, p.n. 679 or 1679 from a tranny shop. You can also get these coolers from Pep Boys. You need about 5 feet more of 11/32" or 3/8" ID hose and a few fittings.

Lately I've been installing B&M plate style coolers on customer cars. They are just as good, but the Hayden is thinner and easier to install.

No, the fluid won't be to cold in the winter. It is true that if you run the fluid to cold you won't be as efficient, but it won't hurt the durability. Besides in the summer, it will thank you. The CV/GM cars are better off than the Mustang and MN12 cars. They run the cooler in the bottom of the radiator, not a separate cooler. So if the engine over heats, so will the transmission. The Crown Vic has a separate cooler and that's actually a tad better.

Anyhow for every 20 degree increase in transmission operating temperature above ideal (which is 160-180 degrees F), the fluid life is
cut in half and so are the internals.

Unit921,

No. I have no plates here. Unless you want to send me your plate and wait for it to return. No Ford does not sell just separator plates.

The '99 main control has many upgrades over the '92-'98 main control, but you still need to open up a few holes in the plate. Not as many mind you.

A plate style cooler is a ton more efficient when compared to a fin and tube. Read Jerry's thesis if you need another opinion.

You do what you want though. I've used a Hayden 30,000 BTU plate style tranny cooler on my '95 T-Bird from day two and it still works today.

A-Train,
Looked through those TCCOA articles a bit. Excellent stuff, pretty involved for those who have not 'swam' in those waters. I never did hear if I just need to replace just the upper spring (to light blue) and the lower spring possibly (or delete it). I don't want to firm a shift, certainly not something that could reduce the life of my drivetrain. It sounds like just the accumulator springs might be just the ticket. It was mentioned above that I definitly have the new upper accumulator, but it was not as clear that I had the lower (2-3). I assume I have neither of the mentioned springs in my 98. Again what is the best description of doing just this accumulator/spring upgrade?

I think I may also try to gear/learn up to do this for my little brother's 95 Grand Marquis. He has been complaining of poor shifting and he definitley has the wrong everything!

After reading quickly through the atricles I found so far I believe I would have to remove the main control plate to do these fixes.

Thanks so much for your all knowing abilities!

L98LS;from what i gather the 1-2 piston is easier to do than the 2-3,with the 2-3 you have to remove the valve body to get to it(going from memory on a previous thread). john/a-train;my trans does a ZING---BAM! once in a while(its only once in a while,this leads me to believe the reg type pan is the calprit.if the spring was broke it would do it all the time,right?

Adam,

Actually, your dog! What's up buddy?

Unit 921,

The 1-2 piston can be removed without dropping the main control, however if you are doing both the 1-2 and 2-3 you must drop the main control. I HIGHLY suggest you replace both the 1-2 and 2-3 if it applies to your vehicle.

To answer your question, yes it could be the flat pan causing the tranny to suck in air. If the spring was broken it would do it all the time not just once and a while. You are correct.

Loaded98LS,

If you are NOT doing the J-Mod to the separator plate, do the following:

1-2: Light blue upper spring, no bottom spring
2-3: Replace the F7AZ-7H292-AA 2-3 accumulator piston with the new updated piston F7AZ-7H292-AB. No spring.

If you are doing the J-Mod at the same time, you want to do the following:

1-2: Light blue upper spring, p.n. F75Z-7F284-AA. Use the following spring in the bottom of the piston, F7AZ-7F284-BA.
2-3: Do the same as above.

I can't remember what was inside the '98 Crown Vic
we did. I think it had the light blue top spring and a pueple bottom spring. Maybe Adam remembers.

Yes you have the new 1-2 accumulator piston. I belive Adam and I will be starting to install the J-Mods again if anyone is interested send me a private message. We are in NJ.

Sorry I don't remember either, but I believe you are correct light blue/purple springs.

ATrain, you say here:

quote:
Now, you most likely already have the new 1-2 accumulator piston (99.9% sure). Since the part went into service in late '97. However, your 2-3 accumulator piston is probably p.n. F7AZ-7H292-AA. You need to change that piston to F7AZ-7H292-AB. That part was updated and the older, new style 2-3 accumulator pistons can leak at their seal. TSB 99-9-6 covers this. ALL 1999 and newer 4R70W's have the F7AZ-7F284-AB part number. Leave the 2-3 spring out, trust me.

So my 98 CV is okay with the 1-2 accumulator piston however my 2-3 accumulator should be changed to:

  • F7AZ-7H292-AB ??
    or
  • F7AZ-7F284-AB ??
What's the difference?? Are they interchangeable on a 98 vintage 4R70W??

Thanks a bunch for the info!!
David

Adam,

Yeah. I wrote it down somewhere.

Hey check your e-mail I sent you something about taking care of the Vette window.

David,

You want to purchase F7AZ-7H292-AB. The older part was F7AZ-7H292-AA, that one is no good. We are talking the new style 2-3 accumulator here, not the aluminum one. If you have an older CV/GM ('92-'97) you want the F7AZ-7H292-AB as well. If you have a late '99 and up, you already have the new pistons.

Also if you have a remaned Ford transmission built between mid 1997 and early 1999 you need to replace this piston as well.

What CAN happen if you don't? It's possible for the seal to leak pressure past the 2-3 piston and cause a delayed or no 2-3 upshift. The new accumulator eliminates this problem. Even if you try to order the F7AZ-7H292-AA, the dealer will always give you the most updated part and "AA" has been superceded with "AB".

I hope this helps,

A-Train

A-Train,
Thanks so much for all the clarifiction. I will definitly do the spring-piston mod. I am wondering about the possibility of sending you the control unit for a few days to do it? This would be if I went with the plate mod (j-mod). I don't know enough about the difference to make a final decision about this but thought I would see if having you do it was an option. My little brother has a 95Grand Marquis HPP and is having some shift quality issues. I was thinking of doing his car as well or maybe we could send you both units?

I think I have a pretty good idea how the simple accumulator/spring upgrade firms up the shifts from stock pre 99'.

What I am curious about is exactly what happens with the full J-mod on these trannys. I know I have read it is damn firm, and does not promote longer life on the drivetrain components. I have also read (I believe) that the newer trannys have some of the mods on the control plate already. I am just wondering, opinion wise, if the net effect of doing the J-mod one the tranny would make it drive so much different that it could be a deturrent when/if selling the car to a 'normal' driver/buyer? Would he or she think it was to ruff or potentially faulty? This opinion, that users of a J-modded trannys could render, would really confirm the impact of the mods overall impact long term.

Again thanks for this super info to all 'in-the-know'. It is absolutely invaluable!

A-Train thanks a bunch for this vital information. I'll be doing the upgrades to the springs and the 2-3 accumulator piston in August (scheduled tranny fluid change).

Do you think I or anybody else for that matter should attempt the separator plate mods too?? I'd be using a drill press and the proper bits for metal. I'm just concerned about taking the main control apart; I've heard all about the balls etc. Also, are special tools required? I'm mechanically inclined and a very meticulous type of individual. Sorry if all these questions are a hassle.

David
