Is Your GMC Savana Shifting Poorly or Stuck in Limp Mode?
A faulty Transmission Control Module (TCM) can bring your hardworking GMC Savana 1500 to a grinding halt. If you’re experiencing erratic shifting, delayed gear engagement, or a persistent check engine light, your van isn’t just inconvenient—it’s unreliable. This VIN-programmed T42 TCM is the definitive solution to restore the crisp, predictable performance your vehicle had when it was new, getting you back on the road and back to work without the high cost and hassle of a dealership visit.
Common Symptoms & Your Solution
When the TCM fails, your van’s computer can’t properly manage the transmission. This often results in serious drivability issues. This module is engineered to resolve these exact problems, including:
- Harsh, jerky, or delayed shifting
- The vehicle being stuck in one gear (Limp Mode)
- Illuminated Check Engine or Transmission warning lights
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift, leading to poor acceleration and fuel economy

Frequently Asked Questions
What does a VIN-programmed TCM actually do?
VIN programming loads your vehicle’s specific software and settings onto the module before we ship it. This ensures it works perfectly with your Savana’s engine, anti-lock brake system, and other computers right out of the box, avoiding compatibility issues and the need for expensive dealer tools.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, installation is straightforward. The TCM is typically located in the engine compartment (on the RH side for the Savana) and is accessible with common hand tools. The entire process usually takes less than 30 minutes.
Will this fix my check engine light for code P0700?
Yes. P0700 is a general transmission fault code that signals the TCM has detected a problem. Replacing a faulty TCM with this programmed unit is a very common and effective solution for clearing P0700 and other related transmission codes.
Do I need to send my old part back?
No. We do not require a core charge for this part. You can keep or dispose of your old module without any hassle or extra fees.
