I am reporting a severe powertrain safety hazard involving my 2022 Chevrolet Blazer at approximately 69,000 miles. The vehicle's 9-speed transmission is experiencing a critical internal hydraulic failure that causes unpredictable and violent lurching. Specifically, there is a severe delayed engagement when shifting into Reverse. The engine revs without moving until the hydraulic pressure suddenly spikes, causing the vehicle to violently slam backwards and catch the gear. Furthermore, the transmission exhibits harsh and slipping shifts while driving forward, specifically violently jerking during the 2nd-to-3rd gear upshift. These exact symptoms align with widely documented hydraulic control and valve body defects in the GM 9T50/9T65 transmissions, which are known to cause harsh shifts, delayed engagement, and flaring between gears. …
