We load the latest GM-certified software tailored exactly to your vehicle’s factory specifications, ensuring every shift point and pressure setting is perfect from the moment you plug it in. This is the key difference between a temporary fix and a lasting repair for your 2006-2007 Buick Terraza Transmission Control Module.

By purchasing this pre-programmed 2006-2007 Buick Terraza Transmission Control Module, you are choosing confidence and getting your family’s daily driver back to peak operational condition without delay.
Frequently Asked Questions
What does a Transmission Control Module do?
The TCM is the main computer for your automatic transmission. It receives data from various sensors on the vehicle and uses that information to control when the transmission shifts gears, how firmly it shifts, and when the torque converter locks up for better fuel economy.
Is this part difficult to install?
For the 2006-2007 Buick Terraza, the TCM is located on the LH strut tower. Installation is generally simple and takes under 30 minutes. It involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order.
Will this TCM fix my specific error codes like P0700?
A P0700 code is a general fault code indicating the TCM has detected a problem. This module is designed to fix issues originating from the TCM itself, which is a very common cause for this and other related codes (like solenoid faults). If the root cause is the module, this part is the correct solution.
Do I need to visit a dealer after installation?
No. Because this module comes pre-programmed to your vehicle’s VIN, there is no need for any additional programming or setup at a dealership. It is a true plug-and-play solution.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to poor fuel economy, unpredictable shifting, and eventually cause severe mechanical damage to your transmission due to improper fluid pressures and shift timing, resulting in a much more expensive repair.
Is a core charge required for this part?
No, there is no core charge for this part. You can keep your old module without any hassle or need to return it.
