Sierra 2500 6.0L V8

  • Automatic transmission
  • 99,898 miles

I bought this truck used and the transmission over heated and went out the first trip I took in it. Cost was 6800 to replace transmission and dealership helped me out. But I read now that there is a known issue with the transmission fluid so I am concerned it will happen again.

Sierra 2500 6.2V8

  • Automatic transmission
  • 7,000 miles

I’ve been to five dealerships (GMC), each time they tell me there’s nothing wrong. There just waiting for the warranty to run out. Should have bought a Ford, they do take care of their customers.
