Frequently Asked Questions
What does a T42 TCM actually do?
The Transmission Control Module (TCM) is the ‘brain’ of your automatic transmission. It uses data from various sensors to control shift solenoids, manage fluid pressure, and lock the torque converter, ensuring smooth and efficient gear changes.
Is this module difficult to install?
For most supported vehicles, the installation is simple. The TCM is typically located in an accessible spot in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors, removing the old module, and installing the new one. No special tools are usually required.
How do I know for sure that my TCM is the problem?
Common signs include erratic shifting, getting stuck in one gear (limp mode), and transmission-related error codes like P0700. While these symptoms strongly suggest a faulty TCM, it’s always best to have a qualified mechanic perform a full diagnostic scan to confirm the issue before ordering.
Will this part fix my specific error code?
This module is designed to resolve a wide range of transmission solenoid, sensor, and communication codes, including the common P0700 family of DTCs. Because it arrives programmed with the latest GM software, it often corrects software-related glitches that cause false codes.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back to us.
What happens if I forget to provide my VIN?
Providing your VIN is essential for the programming process. If an order is placed without a VIN, our customer support team will contact you to retrieve it. We cannot ship the module until it has been correctly programmed to your vehicle to ensure plug-and-play functionality.
