I had Dixie Ford do it to my tranny under warranty

While it will not fix your tranny problems per se, it has improve it a bit. The cold shifting was improved somewhat, when its nice and warm outside, it shifts like a hot knife in butter...
If I were to spend the money, I would say buy yourself 3 bottles of Mobil1 ATF for 1/3 the price and stick in the friction modifier if you wish.
Hope this help.

There's a good walk through in the FAQ section, and tells where everything is. Also has anyone actually replaced the fluid with the Ford synthetic fluid, I'm kind of weary of dumping in the coctail.
Has anyone reported any problems with this mod. My car has 90K on it and this is most likely my next job.
