We have classified the 4 complaints from 2002 GMC Sierra 2500 about POWER TRAIN into the following categories.
I purchase this truck 2/03/17 and have used it until 2 weeks age when the brake lines broke in my driveway, i am having the lines replaced with stainless lines at a cost of about $1200 ( i am not sure of the total cost because it also needs a antilock braking pump which was badly corroded) the fuel lings are also rusted and need to be replaced and also the transmission cooling lines need to be replaced at a cost to be determined later. i have a 1953 chevy pickup that still has good brake lines and the frame is in better shape than the newer ones, if gm looked to the past at the materials & methods they might build a better product rather than the garbage they produce now! i am glad i didn't pay $30-$60,000 for this truck.
The transmission came out of reverse, and would not return. no reverse or drive at all. *tr
First the transmission cooling lines rusted out costing over 400.00 to repair. today the brake lines failed because of rust. this will be a very expensive repair. i was fortunate that i was able to avoid crashing the truck when the brakes failed. *tr
