Frequently Asked Questions
Do I need to program this module after I receive it?
No. This module comes fully programmed to your vehicle’s VIN. It is ready for installation right out of the box, saving you a trip to the dealership and additional programming fees.
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.
Will this fix a P0700 diagnostic 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, it’s essential to check for any other specific codes (like for solenoids or sensors) that are also present. In many cases, replacing the faulty TCM will clear the P0700 code after installation.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The entire process can often be completed in under 30 minutes.
What happens if I continue driving with a bad TCM?
Continuing to drive with a failing TCM can lead to more severe transmission damage. Erratic shifting and pressure control issues can cause excessive wear on internal components like clutches and bands, potentially leading to a much more expensive transmission rebuild.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep your old module without the hassle of returning it.
