Is your GMC Savana 2500 van letting you down with harsh shifts, a check engine light, or getting stuck in gear? A faulty TCM doesn’t just affect performance—it affects your workday. Get your reliable workhorse back on the road quickly with our pre-programmed T42 Transmission Control Module, the definitive solution for restoring your van’s transmission to peak operational health.
Common Symptoms & Your Solution
When the Transmission Control Module (TCM) in your work van begins to fail, it can cause a host of frustrating and costly problems. You might experience sudden, harsh gear changes, a significant delay when shifting from park to drive, or the feeling that the transmission is slipping. Many drivers report their vehicle getting stuck in “limp mode” (usually 2nd or 3rd gear) as a self-preservation measure, severely limiting speed and power. These issues are often accompanied by a check engine light or transmission warning light, with Diagnostic Trouble Codes (DTCs) like P0700 (Transmission Control System Malfunction) or P0750-series solenoid codes. This pre-programmed Savana 2500 transmission control module is the direct, reliable fix for these exact issues, engineered to restore the crisp, predictable performance your work demands.
