This occurred without warning. Immediately after, the transmission defaulted into a fail-safe condition and became locked in 4th gear. The vehicle would move but could not shift properly, resulting in abnormally high RPM and engine load at highway speeds. I was forced to continue driving several miles in this condition to reach a safe exit. The unexpected drivetrain behavior and temporary wheel lockup created a serious safety risk, including potential loss of control and risk of collision. The dealership identified transmission diagnostic trouble codes P2715 and P2733 (pressure control solenoid performance). Transmission fluid was found to be burnt and contaminated with metal debris. The vehicle is subject to GM Special Coverage N242454441 for a known control valve body defect that can cause harsh shifting and reduced engine power. Although code P0747 (referenced in the bulletin) was not present, the failure involved transmission hydraulic pressure control. The dealership is replacing the valve body under the special coverage but is not addressing the internal transmission damage, stating they cannot determine whether the damage resulted from the covered defect. The sudden rear wheel lockup and transmission fail-safe condition at highway speed present a significant safety concern involving unintended drivetrain behavior.","products":[{"type":"Vehicle","productYear":"2021","productMake":"CHEVROLET","productModel":"SILVERADO 2500","manufacturer":"General Motors, LLC"}]}]}
