Frequently Asked Questions
What does ‘VIN Programmed’ actually mean for me?
It means the module is loaded with the specific software and calibration files for your exact Buick Lucerne based on its Vehicle Identification Number (VIN). This makes the installation a simple plug-and-play process, as the part is already configured to work with your car’s engine, tire size, and other options, eliminating the need for a dealership visit.
Is this difficult to install myself?
For the 2006-2011 Lucerne, the TCM is located in the left-hand (driver’s side) engine compartment. Installation involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. Most individuals with basic mechanical skills can complete the swap in under 30 minutes.
Will this part 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 the P0700 and related transmission codes, you should always diagnose any specific solenoid or sensor codes that may be present. After installation, it is recommended to clear all codes with a scan tool.
Do I have to send my old TCM back?
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 both the V6 and V8 Lucerne models?
