My 02 Z71 has 55000 miles. When shifting from 1st to 2nd, I feel a shutter or slip. This only happens when its fully warmed up. I found TSB #020730030(A) which describes this condition and says "Install generator voltage sense circuit".
Anyone heard of this? Local AAmco guy and 2 other shops say they have not.
Also, at 36000 miles the sun shell blew. Dealer fixed that.
Dont know what the next move should be.
