Frequently Asked Questions
What does a Transmission Control Module do?
The TCM is the electronic brain of your automatic transmission. It uses sensor inputs to control shift solenoids, regulate hydraulic pressure, and manage torque converter clutch operation to ensure smooth, efficient gear changes.
Is this module difficult to install?
For the 2006-2009 Pontiac Montana, the TCM is located on the driver’s side (LH) strut tower in the engine bay, making it relatively accessible. With basic hand tools, the process typically takes under 30 minutes. The most important benefit is that our module requires no further programming after installation.
Will this TCM fix my specific error codes?
This module is the correct solution for a wide range of transmission-related DTCs, including the general code P0700 and various solenoid-specific codes (e.g., P0751, P0756). If your diagnosis points to a faulty computer, this part is designed to clear those codes.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe mechanical damage inside the transmission due to incorrect fluid pressure and harsh shifting. This can turn a relatively simple electronic repair into a very expensive mechanical overhaul. It can also be a safety hazard if the vehicle shifts unpredictably or fails to accelerate properly.
Do I need to send my old part back?
No. We do not require a core charge for this part. You can keep or dispose of your old module without any hassle or extra fees.
