2022 Chevrolet Silverado 2500

The vehicle will not allow the truck to be turned off everytime, it states the truck must be in park to be turned off, and the truck is in park. The engine lost power and staleld twice, and loses accelerator power multiple times. The transmission has dis-engaged 3 times. All of this since July 2026. The truck has 54,000 miles on it.

I own a 2022 Chevrolet Silverado 2500HD equipped with the 6.6L Duramax diesel engine and Allison-branded 10 speed (10L1000) automatic transmission. VIN: [XXX]. While pulling away from a traffic light and accelerating to approximately 20 to 30 mph, the transmission suddenly began shifting harshly and erratically, experienced delayed engagement, unexpectedly downshifted, and would not shift into overdrive. At the same time, the check engine light illuminated and a Reduced Engine Power warning appeared. There were no warning lights, messages, or transmission symptoms prior to this incident. I pulled into a parking lot for approximately one hour, but when I resumed driving, the same failure occurred again. The transmission malfunction created a safety concern because the vehicle unexpectedly lost normal shifting and power while operating in traffic, making it difficult to accelerate and maintain speed safely. I contacted OnStar, which reported both an engine and transmission fault. I then drove the vehicle to my independent diesel mechanic, who diagnosed a failure of the transmission control valve body caused by an internal solenoid that is not serviceable separately, requiring replacement of the complete transmission control valve body assembly. The repair has been completed, so the original failed component is no longer available for inspection. The failure was confirmed by an independent service center. The vehicle has not been inspected by Chevrolet, law enforcement, or an insurance representative. I contacted General Motors to determine whether my VIN was included in the existing transmission control valve recall and was advised that it is not. I am submitting this complaint because my truck experienced the same symptoms and the same component failure as vehicles covered by the recall, despite my VIN not being included. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The Transmission on my truck down shifted and made it so I lost all power while driving. If I would have been on the freeway it probably would have killed me or caused a serious accident. It is at a shop waiting to be inspected but they said it was the valve body in the transmission. No warning lights came on at all, and the shop had to plug a computer into my transmission to get the codes. GM needs to make this right because it is going to kill someone or cause harm if a bad accident happens due to failure at freeway speeds.

Transmission Control Valve Body (Recall #N242454440) ​Your truck is part of the massive recall issued late last year (expanded in February 2026) regarding the 10-speed Allison transmission. ​The Problem: Internal wear in the valve body causes a drop in pressure, which can cause the rear wheels to lock up suddenly while you're driving. Multiple occurrences. It has been taken to the shop for this issue.

So the electrical would be when I shut my truck off in park I cannot turn my key completely back to release the key so therefore I’m killing my battery leaving the power on as far as the tires they’re rated for 50 or 55,000 miles I have 37,000 miles and I have no tread left and as far as my drivetrain when accelerating onto a highway pulling my fifth wheel camper that is 16,000 pounds loaded the truck box really bad as far as the crash warning breaking system it does not break

When vehicle is placed in park the safety lock will not allow the key to turn to the "off" position and be removed. The vehicle will not turn "off" any further than the accessory position. Sometimes after turning the steering wheel back and forth while working the ignition the key will release. If this does not work after a minute or so, sometimes you can start the truck and immediately turn it all the way off and get the key to release. If all of that fails the last option is to disconnect the battery. It is an intermittent issue that will happen 5 times a day for a week, and then will not replicate again for a week or two.

I have a 2022 Chevrolet Silverado 2500 HD diesel truck. Twice while driving uphill the transmission seemed to lock up with a very “jerky” move. GM has acknowledged this problem and has issued a recall. I have taken my truck and have had the recall “remedy” performed. However, THIS REMEDY IS A BAND AID NOT A SOLUTION. The remedy/recall is only reprogramming the computer that controls the transmission to warn the driver that the problem is about to occur and will limit the speed of the vehicle to not exceed the fifth gear until the problem is repaired. I feel the transmission issue should be addressed in the recall not delayed until the issue re-occurs. As per a letter I received from GM the repair that’s needed is Special Coverage N232395330 is the replacement of Transmission Valve Body.
