Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the biggest benefit of our product. We program the module to your vehicle’s specific VIN before shipping it. It arrives ready for a true plug-and-play installation, saving you time and money.
Where is the TCM located on my vehicle?
Location varies by model. On many trucks and SUVs like the Silverado and Tahoe, it’s found in the engine compartment next to the battery. On other vehicles, it may be on the LH strut tower or near the air cleaner box. The installation is straightforward and typically takes less than 30 minutes with basic hand tools.
Will this fix my P0700 error code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, it’s important to use a scan tool to check for other specific codes (like solenoid faults) that the P0700 is reporting. This module is designed to fix those common internal electronic failures.
Is this the correct part for vehicles other than a Silverado?
Absolutely. This T42 TCM is compatible with a massive range of 2006-2014 GM vehicles, including the GMC Sierra, Yukon, Chevrolet Tahoe, Suburban, Express Van, Impala, Hummer H3, and many more. Please check the detailed fitment list to confirm compatibility with your specific year and model.
Do I need to return my old part (core)?
No, there is no core charge for this part. You can keep or dispose of your old module without the hassle of returning it, making the repair process even simpler.
