Best upgrades
What would be the best upgrades for my tranny in my 2000 sierra Z71. I want harder shifts, the only thing i tow are my two quads on a small trailer so i am not trailing anything big. I know a shift kit will help me but what else can i do?

Re: Best upgrades
well if you get the transgo hd2 shift kit you will get harder/quicker shifts but a transmission rebuild will be in order soon. A good cheap and easy upgrade would be the corvette servo(under 20 bucks) if you do plan on getting a shift kit get a transgo sk or superior shift kit. If you will be rebuilding soon get the transgo hd2 kit. I installed the transgo hd2 kit in my 4L60e at around 20,000 miles. 23,000 miles later I busted the sunshell in it. Had to get the transmission rebuilt. it was not cheap. the HD2 shift kit is brutal on the 1-2 shift.
