Is Your GM Vehicle Shifting Erratically or Stuck in Limp Mode?
Dealing with transmission problems can be one of the most frustrating and concerning issues for any vehicle owner. A faulty Transmission Control Module (TCM) can turn a dependable daily driver or a hardworking truck into an unreliable liability. If you’re experiencing harsh shifts, delayed gear engagement, or have a persistent check engine light, you’ve come to the right place for a permanent solution. This OEM-quality T42 Transmission Control Module is the definitive fix, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.

Expert Insight: The Critical Importance of VIN Programming
Many drivers and even some repair shops make the mistake of installing a used or generic TCM without proper programming. This almost always leads to continued shifting problems, communication errors with other vehicle modules, and a car that still won’t operate correctly. The vehicle’s computer network relies on the VIN to verify that the correct components are installed. Our pre-programming service removes all guesswork and extra steps. We load your vehicle’s specific calibration files onto the module before it ships, making the installation as simple as swapping the part. This is the single most important factor in a successful TCM replacement.
Frequently Asked Questions
What information do you need to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) at checkout. This allows us to load the exact factory calibration and software for your specific make, model, and year, ensuring perfect compatibility.
Is this installation difficult? Can I do it myself?
For most models, the installation is straightforward and can be completed in under 30 minutes with basic hand tools. The TCM is typically located in the engine compartment.
