It might restore your car to proper driving habits, but thats if the clutches aren't too burned. Dexron III/Mercon gets too hot in these transmissions and break down, causing shudder (usually only in the TC though), and Mercon V is formulated for the higher temps and such.

You can buy Mercon V at your local Dealership or Autozone. Just poke around through the various auto parts suppliers in your area and you're bound to find it.

I have found the best prices to be at advance auto/checker.

They carry the havoline brand, it is 2.64 a quart if I recall correctly.

You might want to call them in advance, because most stores don't carry more than ten or so bottles.

I had to have them order a couple cases for me when I was doing my tranny flushes on multiple cars.

does it really work?
we acutally spent alot of money replacing the tranmission at 40K miles.. and it didnt change anything...
It seems silly that a 50$ doller bottle worked better than a 1000$ trany. :(

The shuddering is much worse on 94-5 cars than later ones. The 96 should be able to live longer after getting it (assuming its not worn out like AJ posted).
baseer, did they replace the torque converter when they replaced the tranny?

Well if the TC is shuddering, it doesnt matter what transmission you have or if you had none at all... the problem IS the TC, not the tranny.
As for tranny coolers, you want a nice stacked plate type cooler. This reduces the heat in the transmission. Heat leads to TC shudder and clutch wear. like the OD 101 article states 'If cars had adequate transmission cooling from the factory, it would put most tranny shops out of business.'

btw: keep an eye on the fluid condition. if it starts to turn brown/black get that TC replaced ASAP.

If the fluid doesn't fix the problem, or if the fluid reduces the problem (without eliminating it) I'd replace the torque converter. The fluid will generally fix the problem, but sometimes the torque converter clutch is just too far gone for the fluid to stop it.

Also, if you haven't already added an aftermarket transmission cooler, buy this one.

Then you can follow Jesse's install instructions here and you'll be set. You can generally get a Lincoln Mark VIII troque converter (new) for a good price and that'll both fix a TC shudder problem and also help the performance of the car as well.

Baseer,

Mercon V did fix my problem. I bought my Mercon V through a Ford Dealer that gives us a club discount. I also put in a transmission cooler from www.bulkpart.com. Mine is lighter than the B&M, but my transmission runs cold with the Jmod done to it. Right now, I have cardboard blocking the tranny cooler to keep the tranny from getting too cold here.

Some places that do transmission flushes the right way (Motor running, etc), will put in Mercon V if you ask. My local shop would do it no extra charge.
