Frequently Asked Questions
What does a Transmission Control Module do?
The TCM is a computer that collects data from various sensors in your vehicle’s engine and transmission. It uses this information to control when the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smooth operation.
Is this TCM difficult to install on my Buick Terraza?
Installation is straightforward for a DIYer with basic tools. On the 2006-2007 Terraza, the TCM is typically located on the LH strut tower. The process usually takes under 30 minutes. Always disconnect the battery before starting the installation.
Do I need to program this module?
No. This is the key benefit of our product. We pre-program the module to your vehicle’s VIN before shipping, so it arrives ready for a plug-and-play installation. No additional programming or dealership visits are required.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a faulty TCM is a very common cause, this code can also be triggered by other issues. However, if you’re experiencing shifting problems along with a P0700 code, replacing the TCM is the most likely solution.
What is the difference between a TCM and a PCM?
The TCM specifically controls the transmission, while the Powertrain Control Module (PCM) is the main computer that controls both the engine and, in some vehicles, the transmission. In many GM vehicles like the Terraza, these are separate units.
Is a core charge required for this part?
No, there is no core charge. You can keep or dispose of your old part without any additional fees or return processes, making your repair as simple as possible.
