i got a 90 jimmy with 81,000 miles on it. I got a 700r , i think it might be going bad. the owner before me put a shift kit in it, when i put it in drive it jumps in to gear, and when am in reverse or neutral there is a clicking noise. when i hit the gas it seens kind of ruff. is t /forums/images/graemlins/confused.gifhere some kind of rebuild kit or something that i can put in or much much will it cost to get it rebuild somewhere
