Problem overview

Some Chevrolet Express 2500 owners report experiencing ongoing transmission problems even after a new installation, including issues like torque converter failure and gear shifting difficulties. These persistent issues may be linked to low or insufficient transmission fluid, which can cause slipping gears. Additionally, some owners find that specific technical service bulletins from Chevrolet, such as those instructing technicians to inspect and replace the transmission Control Valve Body Spacer Plate, may address certain problems. The quality of replacement parts, particularly if a remanufactured transmission was used, can also affect performance. Effective communication with the dealership or Chevrolet Customer Care is essential, especially since parts may be backordered, causing repair delays. For those facing repeated transmission issues, exploring legal options under the California Lemon Law may be advisable for potential compensation or vehicle replacement.
