My friend used to have a Buick Regal with a bulletproof tranny and some major engine work and told me I should look into getting one because it would really help if I got one if I didn't wanna do a manual swap. Anybody know any real info on this. I'm really considering getting this with a valve body kit and torque converter from Max Tuning. I know Aaron says the torque converter really gets the Max moving but I wanna find out if anybody else has any opinions or info on it or has it done.
