Frequently Asked Questions
Do I need to program this module?
No. We program the module to your vehicle’s VIN before shipping it to you. It is ready for a plug-and-play installation as soon as it arrives, with no additional programming or dealership visits required.
Where is the TCM located on my Pontiac Montana?
On the 2006-2009 Pontiac Montana, the Transmission Control Module is typically located on the LH (driver’s side) strut tower in the engine compartment. Installation is straightforward and generally takes less than 30 minutes.
Will this fix a P0700 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 crucial to diagnose any other codes that appear alongside P0700. Replacing a faulty TCM is a very common fix for this code.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job. It involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one. Always disconnect the battery first to ensure the system resets properly.
What happens if I don’t replace a bad TCM?
Continuing to drive with a failing TCM can lead to more severe and expensive transmission damage. Poor shifting can cause excessive wear on internal components like clutches and bands, potentially leading to a complete transmission failure that requires a full rebuild or replacement.
