I have been experiencing trasmission problems. The vehicle jerks, shutters and makes numerous thumping sounds during acceleration as well as at certain constant speeds. It frequently make a lound clunking sound when first put in drive and beginning to move. On January 16, 2025, I took the truck to Rubideaux GMC, 351 W Dalton Ave, Hayden ID 83835, for inspection. I was told that the torque converter "was shot" and that the transmission fluid was scorched and there metal shavings in the transmission filter. The service manager informed me that I needed a new transmission at a cost of $7,000. the dealer told me that they will have to find a remanufactured replacement which by their description are in short supply. I went to an independent shop in the area and was quoted a similar price. The employee also advised me of a class action law suite that was in process for 2016-2020 GM trucks and SUV's and passenger cars equipped with the model 8L transmission with the same problem. Several suits are under way including, [XXX] et al v GM, I find this situation especially concerning given the very gentle treatment Ive given this vehicle since I purchased it new. The truck only has 63,000 miles on it and I have never towed anything with this vehicle nor carried any load of more than a couple oh hundred pounds in the bed of the truck. What component failed? Transmission. The transmission is still in the truck pending available replacement. How was your safety put at risk? The transmission could fail while driving causing a lack of vehicle control. Has the problem been reproduced by a dealer? Yes it was confirmed by the dealership listed above. Has vehicle been inspected by the manufacturer, police, or insurance? It has been inspected by a licensed GMC dealer. Where there any warning lamps, messages or other symptons.....?
