why dont you stick to picking on V6's
why, the trans works perfectly when its in drive. if i dog on it in tap shift it starts to slip and gears start to bang. i have heard of alot of people to tare up there trans in tap shift. even trannyman, the guy that is probably the best 4t65e builder, will void your warrenty if you manually shift the valve body. thats got to say something.
