2023 CHEVROLET SILVERADO 3500 Complaints

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
