Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not. We handle all the programming before it ships. Just provide your vehicle’s VIN during checkout, and the 24238856 T42 Transmission Control Module will arrive ready for a simple, plug-and-play installation.
What are the most common signs of a bad TCM?
The most common symptoms include harsh or delayed shifting, the vehicle being stuck in one gear (limp mode), the check engine light illuminating with codes like P0700, and a general decline in transmission performance and fuel efficiency.
Is this part difficult to install?
For most DIYers with basic tools, the installation is straightforward and typically takes under 30 minutes. The TCM is usually located in the engine compartment. We recommend disconnecting the battery before starting and using a scan tool to clear any stored codes after installation is complete.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe issues. Continued harsh shifting can cause premature mechanical wear on internal transmission components, and being stuck in limp mode can be a significant safety hazard. Prompt replacement is key to preventing more costly repairs down the road.
How do I provide my vehicle’s VIN?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. This is crucial for us to program the module correctly for your specific vehicle configuration.
