- Failure to upshift or downshift correctly
- Noticeably poor fuel economy
- Complete loss of communication with the transmission
Installing this pre-programmed module directly addresses the root electronic cause of these problems, restoring the precise communication needed between your engine and transmission for smooth, efficient operation.

Expert Insight: The Critical Role of VIN Programming
Why is VIN programming so important? A generic, non-programmed TCM doesn’t know your vehicle’s specific configuration—like its engine size, axle ratio, or tire size. This mismatch leads to poor shifting, incorrect performance, and can even cause long-term damage to your transmission. Our process ensures the Programmed T42 TCM 24235340 is a perfect electronic match for your vehicle, saving you hundreds of dollars in dealer fees and preventing the headaches of a failed installation.
Frequently Asked Questions
What does a T42 TCM do?
The Transmission Control Module (TCM) acts as the brain for your automatic transmission. It uses data from various sensors to control shift solenoids, manage torque converter clutch lockup, and regulate fluid pressure, ensuring smooth and efficient gear changes.
Is this part difficult to install?
Installation is generally straightforward for a DIYer with basic tools. The module is typically located in the engine bay and can be replaced in under an hour. Since it comes pre-programmed, no special electronic tools are needed. Just disconnect the battery, swap the module, and reconnect.
How do I know for sure if my TCM has failed?
Common signs include erratic shifting, getting stuck in limp mode, and specific transmission-related diagnostic codes (like P0700). If you are experiencing these issues, especially after checking the transmission fluid and connections, the TCM is a very likely culprit.
What happens if I don’t provide my VIN when ordering?
Providing your VIN is essential. Without it, we cannot program the module, and it will not function correctly in your vehicle. Please enter your 17-digit VIN during checkout to ensure a plug-and-play installation.
