Transmission / Electronic Shifter Control While attempting to operate my 2023 Chevrolet Suburban, the vehicle suddenly suffered a complete transmission shift lockout, displaying a critical driver alert on the dashboard stating: "Conditions Not Correct for Shifting." The vehicle actively blocked and refused engagement into Reverse gear. A diagnostic scan revealed (P0776) transmission solenoid and hydraulic control codes, and the Chevrolet owner's application triggered a "Service Engine/Transmission" warning. This issue is identical to the widespread, known manufacturing defect involving premature wear of the 10-speed transmission control valve body. General Motors has already acknowledged…

…An independent mechanic inspected the transmission and found diagnostic trouble codes P0747, P0776, and P0700 related to transmission pressure control and valve body operation. Inspection also revealed significant metal contamination, sludge, and clutch material inside the transmission pan and filter. Reverse and 2nd gear were determined to be failed/burnt internally. The vehicle was later transported to an authorized GMC dealer for inspection. Dealer confirmed reverse gear would not engage even after adding transmission fluid. Vehicle is currently available for inspection.

The vehicle experienced a transmission control malfunction related to a transmission solenoid (diagnostic code P0776).

The vehicle was inspected by General Motors on November 3, 2025, at…

I was driving down the road and my vehicle went into limp mode, and I had reduced acceleration. I got to my destination then could not reverse the vehicle out of the parking space, reverse would not engage and allow me to have acceleration power. Because the parking space was on an incline we could roll backwards then drive forward, in limp mode, to a nearby mechanic. The vehicle diagnostic codes they got were: no reverse, p0700, p0776 and p18a1. They told us the repair needed would be to remove and replace the valve body assembly for $2,862.40. There were no warning lights that came on prior to the incident. Once the vehicle went into limp mode the check engine light came on. We had a Chevy…
