Get Your Vehicle Shifting Smoothly Again
Is your GMC Canyon, Chevy Silverado, or other GM vehicle suffering from harsh, erratic shifting, getting stuck in gear, or throwing transmission codes? A faulty Transmission Control Module (TCM) is often the culprit, disrupting communication and causing significant drivability issues. This T42 TCM, service number 24256960, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation that gets you back on the road with confidence.

- An illuminated Check Engine Light or Transmission Warning Light.
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- A complete failure to upshift or downshift, leading to poor acceleration and fuel economy.
