I have an 06 GP GT that is supercharged. It has 34,000 miles on it and I am going to be changing the transmission oil/filter (no flush) and would like to install a shift kit. My questions are:
1. Which one? ZZP? Wbody? 3800 Performance? Other?
2. Are they all the same?
3. Are any computer mods required?
I'm not interested in building my own, I just want to buy the parts and put it in while I'm there.
