Frequently Asked Questions
What does a T42 TCM do?
The Transmission Control Module (TCM) acts as the computer for your automatic transmission. It receives data from various sensors on the vehicle and uses that information to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smoothness.
Is this part difficult to install?
For most DIYers with basic tools, installation is straightforward. The TCM is typically located in the engine compartment and can be replaced in under 30 minutes. Since our modules come pre-programmed, the most complex part of the job is already done for you.
Do I need to take my car to the dealer after installation?
No. The primary benefit of this module is that it is pre-programmed to your VIN. This eliminates the need for any additional programming or setup from a dealership, saving you significant time and money.
How do I know if this TCM will fit my vehicle?
Please refer to the detailed compatibility list on this page. You can also match the service number from your original TCM to the part numbers listed in our description to ensure a perfect fit for your specific make and model.
What happens if I don’t replace a bad TCM?
Ignoring a failing TCM can lead to more severe transmission damage. Continued erratic shifting can cause excessive wear on internal components like clutches and bands, potentially resulting in a complete transmission failure that is far more expensive to repair.
What is a “core charge” and why don’t you have one?
A core charge is a deposit that other sellers charge to encourage you to return your old, faulty part. We simplify the process by not requiring a core return, which means no extra deposit, no return shipping, and no waiting for a refund.
