idk how the reprogramming kit works so maybe someone has some useful info or better yet has one? both kits do pretty much the same but i'm guessing the reprogramming kit works through the tcm?

 

The reprogramming kit has nothing to do with the TCM. I have it and it's a VB mod. I would think that the reprogramming kit is similar to a Stage II VB mod. The 1-2 shift is very firm, 2-3 is also quite noticeable, and lockup is also very firm. When I had the 3L VQ I could squeal 1-2 no problem. Just a warning, if you dont like real pronounced and hard shifts, stay away from this kit.

Differences:

Reprogramming kit:

thanks man. it was a toss up but now i'm sure i'll go with the reprogramming kit especially that it mentions turbo.
was it hard to install/did it come with instructions or did you have someone put it in?

 

SupraStick

 

thought about it after i saw your setup but...after a whole day of shifting my big truck i want a full AT so i can have a beer in my free hand on the way home - jk.

 

it comes with instructions but I still had a reputable transmission shop put it in. I've heard of too many horror stories where people have messed up their tranny trying to install the kit. And Dave is right, Suprastick is the way to go.

 

suprastick wouldn't be bad but if i was to shift i'd swap in a mt.

 

the Suprastick has a manual and automatic mode.
