2023 Chevrolet Silverado 3500

The valve body assembly is not letting it to shift right when driving from 50mph to 60 mph it has a clunking noise I have it replaced and is still not working correctly GM knows there is a problem with the 10 speed transmissions I have a 2023 3500 diesel with the same problem as the recalls on the 2020 to 2022 years It is doing the same thing as the 20,21 22 transmissions are having.

Engine started running extremely rough shaking vehicle. Various warning lights lit up. Took vehicle to dealer and was told that I need a new duramax engine because the cylinders are scored. Vehicle has about 58k miles It has been at the dealer for 3 weeks and they say they have no idea when they can get it fixed. It is my only work vehicle and now I have to rent another vehicle to keep working.

Driving on highway at 40mph while towing a trailer the rear tires briefly locked up, then the Check Engine Light came on and vehicle went into limp mode. Dealer confirmed transmission valve body issue. Same problem as recalled on earlier model year vehicles. Seems like 2023-2025 vehicles should be added to the original recall to ensure support and long-term warranty protection.

TRANSMISSION UNEXPECTEDLY DOWN SHIFTED HARD. VEHICLE HAD TO BE TOWED- HIGH RPM/LOW SPEED/HIGH TRANSMISSION TEMPS. DEALER STATED THIS IS A KNOWN PROBLEM WITH THIS TRANSMISSION - CONTROL VALVE BODY. TRANSMISSION DOWN SHIFTED HARD CAUSING REAR TIRES TO CHIRP. FORCE ON DOWN SHIFT WAS INTENSE AT 25MPH. IT WAS SO INTENSE MY WIFE AND I THOUGHT OUR VEHICLE WAS REAR-ENDED. THIS IS A HUGE SAFETY ISSUE. THIS COULD HAVE BEEN TRAGIC IF I WAS TRAVELING AT HIGHER SPEEDS OR TOWING MY 5TH WHEEL TRAILER. PER DEALER - THIS IS A KNOWN TRANSMISSION ISSUE WITH GM/CHEVROLET. NO REPLACEMENT PARTS ARE AVAILABLE. MY VEHICLE HAS BEEN SITTING AT THE DEALERSHIP FOR FIVE WEEKS NOW. THERE WERE NO WARNING LAMPS, MESSAGES OR OTHER SYMPTOMS PRIOR TO FAILURE. TO SIDE ON CAUTION, GM/CHEVROLET NEEDS TO RECALL THESE VEHICLES BEFORE SOMEONE GETS SERIOUSLY HURT AND/OR KILLED. I'M TOLD GM/CHEVROLET/ALLISON REPLACED METAL BALLS WITH PLASTIC BALLS IN THIS VALVE CONTROL BODY AND HEAT IS SHRINKING THE PLASTIC BALLS CAUSING THE PROBLEM.

Vehicle went into limp mode (max 3rd gear and about 45mph) while entering the interstate pulling a 30' 5th wheel camper. Luckily was in a construction zone so the speed limits was posted at 55 so no one took me out. Got off the next offramp and took vehicle to Chevy dealership and they said a Control Solenoid Valve Body in the transmission failed. All parts on nationwide backorder with no approximation of updated part. Looked into this online and it looks like it's been an issue for 4 years plus
