My truck has had transmission issues since we purchased it. At 79,000 miles the factory transmission finally went out and needed replaced. The truck currently has 81,000 miles on it and is already having transmission problems with the rebuilt parts. Background: the truck began having hard downshifts since purchase. Over the course of our ownership, we noticed it started struggling with shifting from 2nd gear to 3rd and 3rd gear to 4th. Constant ‘clunking’ and shuttering when trying to shift. Approximately November of 2024 the truck suffered from the known GM transmission failures. It was almost ‘skipping’ upon acceleration and had a very hard time with cycling between gears. The transmission began making a sound comparable to a normal operating diesel truck (almost sounded like the turbo engines upon acceleration). The truck was sent to the dealership and the transmission was replaced. However, since this replacement we are now experiencing similar symptoms to the previous transmission. There is a very hard downshift, there is clunking sound when the truck is trying to go from 3rd to 4th, and the truck has a noticeable gear burning smell when driven long distances.
