Frequently Asked Questions
What does a Transmission Control Module do?
The TCM acts as the brain for your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses this information to control when the transmission shifts gears, when the torque converter locks up, and to monitor overall transmission health.
Is this part truly plug-and-play?
Yes. Because we program the module to your vehicle’s exact VIN before shipping, it is ready for installation immediately. No further programming or trips to a mechanic or dealership are required. Simply install the part, disconnect the battery for 15 minutes to clear any adaptive memory, and you’re ready to drive.
Will this fix my P0700 error code?
A P0700 code is a general fault code indicating the TCM has detected a problem. This module often resolves the underlying issues that cause a P0700 code, as well as more specific solenoid or shifting codes. After installation, be sure to clear all codes with a scan tool.
Where is the TCM located on my 2006-2007 Buick Terraza?
On the Buick Terraza and similar GM minivans like the Uplander and Montana, the Transmission Control Module is typically located on the driver’s side of the engine compartment, mounted to the LH strut tower. Always disconnect the vehicle’s battery before attempting removal or installation.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep, recycle, or dispose of your old module at your convenience, making the repair process simpler and faster.
What happens if I provide the wrong VIN?
Providing the correct VIN is critical for proper programming. An incorrect VIN will lead to compatibility issues and improper transmission function. Please double-check your VIN from your driver’s side door jamb or dashboard before placing your order to ensure a successful repair with your new programmed 2006-2007 Buick Terraza transmission control module.
