Frequently Asked Questions
Will this part definitely fix my shifting problems?
If your vehicle is exhibiting common symptoms like erratic shifting, limp mode, or specific transmission-related fault codes (like P0700), a faulty TCM is the most common cause. This module is designed to be the direct solution for these electronic failures. However, we always recommend a proper diagnosis by a qualified mechanic to rule out any mechanical issues within the transmission itself.
Is this part difficult to install on my Lucerne?
Installation is generally straightforward for someone with basic mechanical skills. On the 2006-2011 Lucerne, the TCM is typically located in the LH (driver’s side) engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It often takes less than 30 minutes. No special programming tools are required.
What does ‘VIN Programmed’ mean for me?
It means convenience and savings. We take your vehicle’s VIN and load the latest GM software specific to your car onto the module before it ships. This makes the unit truly plug-and-play. You can install it yourself or have your local mechanic do it, completely avoiding the extra cost and hassle of having a dealership program it after installation.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep, recycle, or dispose of your old module without any obligation, simplifying the repair process for you.
