Is Your Work Van Sidelined by Transmission Problems?
For a business owner or tradesperson, a Chevrolet Express 2500 that won’t shift correctly isn’t just an inconvenience—it’s a direct hit to your bottom line. Harsh shifting, getting stuck in limp mode, or a persistent check engine light means lost time, canceled jobs, and mounting frustration. Get your van out of the shop and back on the road with this fully programmed T42 Transmission Control Module (TCM), the definitive solution for restoring your transmission’s performance and reliability.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing TCM is the most likely culprit. This module is engineered to be the direct fix for these exact problems:
- Erratic or Harsh Shifting: Abrupt, jerky gear changes or delayed engagement from park to drive.
- Stuck in Limp Mode: The vehicle refuses to shift past 2nd or 3rd gear as a protective measure.
- Warning Lights: A check engine light or transmission warning light is illuminated on your dash, often with diagnostic trouble codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- Poor Performance: A noticeable drop in fuel economy, failure to upshift or downshift, or a transmission that seems to be slipping.
Installing our pre-programmed 2006-2014 Express 2500 transmission control module directly addresses the electronic source of these failures, restoring crisp, factory-spec shifting and clearing persistent fault codes.
