Re: Transgo Shiftkit
Couple of things here:
-You have a 4r70w tranny in your 2000.
-I've heard nothing but BAD THINGS about that shift kit.
-There is no mild shift kit in the P71s. Only the PCM programming is slightly different to give the tranny a higher shift point and firmer shift (raises line pressure).
If you want your tranny to shift the way it should, do a J-Mod. J for Jerry. He was one of the engineers in designing our trannys and has released what can be done to make the trannys mechanically more efficient and shift firmer. This can be found online. crownvic.net has a write up on how to exactly do it in their 'Body of Knowledge' room. It involves dropping the valve body and removing some springs and also drilling larger holes in the separator plate. This is a safe and proven way to improve your tranny. You can also order a programmer. lonnie @ blueovalchips.com tunes a lot of Panthers. With his tuning he can electronically make the tranny shift much better and efficiently. Not to mention other performance gains you would get from adjusting other aspects of the vehicle. The best set up would to do the j-mod plus have a tune.
