Frequently Asked Questions
Do I need to take my van to a dealer after installing this part?

Where is the TCM located on a 2006-2007 Buick Terraza?
On the Buick Terraza and its platform mates (like the Uplander and Montana), the Transmission Control Module is typically located on the driver’s side of the engine compartment, attached to the LH strut tower.
Is this installation difficult for a DIY mechanic?
The installation is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order.
