Frequently Asked Questions
Why is VIN programming necessary for this TCM?
The TCM must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) to ensure it communicates correctly with the Engine Control Module (ECM) and other systems. This programming sets correct shift points, line pressures, and other critical parameters for your Terraza’s specific configuration.
Is this part difficult to install on my 2006-2007 Terraza?
Installation is straightforward for a DIYer with basic tools. On the Terraza, the TCM is located on the driver’s side strut tower. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. The entire job typically takes less than 30 minutes.
Will this module fix my P0700 check engine light code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. In many cases, a faulty TCM is the root cause. Replacing the module with this pre-programmed unit will often resolve the P0700 code and any related transmission-specific codes. We always recommend clearing all codes with a scan tool after installation.
