You’re not just buying a component; you’re buying a complete, hassle-free solution that restores your vehicle’s factory performance right in your own driveway.
Frequently Asked Questions
What does ‘VIN programmed’ mean?
It means we use your vehicle’s 17-digit Vehicle Identification Number (VIN) to load the precise software and calibration files from GM onto the module before we ship it to you. This ensures it works perfectly with your vehicle’s specific engine, transmission, and options right out of the box, with no further programming required.
Is this part difficult to install?
Installation is straightforward for anyone with basic mechanical skills. The TCM is typically located in the engine bay and is accessible. The process usually involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Most installations take under 30 minutes.
Will this fix my P0700 error code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. While this VIN programmed T42 TCM often resolves the root cause of the P0700 and related codes, it’s always best to have a full diagnostic scan to confirm the TCM is the faulty component.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module, making the repair process simpler and more convenient for you.
