well i finally broke down and bought the gmm rip shifter, and yesterday while me and my buddy had the exhaust riped off we also droped in the rip shifter and some royal purple. we didn't find the install to be as bad as some have stated. but having 2 people to do the job does make it alot easier. it took about a hour to hour and half with the oil change to complete. before we put the shifter back on we poured the oil in the tranny through the shifter hole to make life easier. in the end all i can say is wow what a diffrence.well worth the money and can't ever be compared to that peice of rubber the factory calls a shifter.
