The contact owns a 2017 GMC Sierra 3500. The contact stated that while shifting from park(p) to drive(d), the engine revved, but the vehicle failed to move forward. There were no warning lights illuminated. The vehicle was towed to a certified mechanic, who determined that the vehicle needed to be diagnosed by a dealer. The mechanic was able to shift the transmission into manual drive mode, allowing the contact to drive the vehicle to the residence. The dealer was contacted and informed the contact that the VIN was not under recall. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact back to the dealer for assistance. The failure mileage was approximately 120,000.
The 6l90 tranmission failed with no warning at 58,408 miles. Had to back the truck up in traffic over 1/2 mile to reach a safe spot. Seems gm is having a lot of problems with this transmission and their 8 speed transmission. No assistance from gm to repair seeing I was out of the 5 year 100000 warranty. Seems gm know about theses problems. Had to spend $5k to get no dealer service to install a remanufactured trans, hoping it will not happen again.
