Frequently Asked Questions
How do I provide my vehicle’s VIN for programming?
After placing your order, you will be prompted to provide your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we have this information, as each module is custom-programmed for a specific vehicle.
Is this part difficult to install?
For the Buick Lucerne, the TCM is typically located in the engine compartment on the driver’s side, making it accessible. Installation is straightforward for someone with basic mechanical skills and usually takes under 30 minutes. We recommend disconnecting the battery before starting the repair.
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, it’s essential to have the vehicle scanned for other specific codes (like solenoid or sensor codes) to confirm the TCM is the primary point of failure. This part is designed to fix internal TCM faults that trigger these codes.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep or dispose of your old module, making the process hassle-free.
Is this compatible with other GM vehicles?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 GM vehicles. While this listing is for the 2006-2011 Buick Lucerne transmission control module, it also fits models like the Impala, Tahoe, Sierra, and many others. The key is the VIN-specific programming that makes it work perfectly for your application.
