Get Your Work Van Back on the Road, Fast.
Is your 2006-2014 GMC Savana 2500 experiencing erratic shifting, getting stuck in gear, or showing a check engine light? A failing Transmission Control Module (TCM) can bring your work to a grinding halt, costing you time and money. This genuine GM T42 TCM, service number 24241806, is the definitive solution. It arrives pre-programmed to your van’s specific VIN, eliminating the need for expensive dealership visits and allowing for a straightforward, plug-and-play installation to get you back on the job without delay.
Common Symptoms & Your Solution
If your Savana is your livelihood, you can’t afford guesswork. A faulty TCM is often the culprit behind frustrating and costly transmission issues. Watch for these warning signs:
- Harsh or Delayed Shifting: Abrupt, clunky gear changes or a noticeable lag when shifting out of park.
- Limp Mode Activation: The vehicle is stuck in a single gear (usually 2nd or 3rd) to prevent further damage.
- Warning Lights: A persistent Check Engine Light or Transmission Warning Light on your dash.
- Diagnostic Trouble Codes (DTCs): Scan tools may show codes like P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0750-P0758).
- Poor Performance: A sudden drop in fuel economy, inability to upshift or downshift, or transmission overheating.
Installing this professionally programmed T42 module directly addresses these problems at their source, restoring the precise, reliable shifting your work van needs.
