Frequently Asked Questions
What does “VIN Programmed” actually mean for me?
It means the module arrives ready to install with no extra steps. We use your vehicle’s unique 17-digit Vehicle Identification Number (VIN) to load the correct factory software and calibrations onto the module before we ship it. This makes the installation truly plug-and-play and saves you a trip to the dealership for expensive programming.
Is this difficult to install on my Avalanche?
No, installation is quite straightforward for someone with basic mechanical skills. The TCM is located in the engine compartment, typically next to the battery. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. Most people can complete the job in under 30 minutes.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s essential to have the vehicle scanned for other, more specific codes (e.g., solenoid circuit faults) to confirm the TCM is the issue. In many cases, replacing a faulty TCM will clear this and related codes.
Do I need any special tools for this job?
Basic hand tools like a socket set and ratchet are all that’s typically required to remove and replace the module. We also recommend using a scan tool to clear any stored trouble codes from the vehicle’s memory after the installation is complete.
Is this part compatible with other GM trucks and SUVs?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 General Motors vehicles, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and many others that use a 4-speed automatic transmission like the 4L60E or 4L70E. The key is our VIN programming, which tailors it to your specific model.
