Expert Insight: The Importance of Correct Programming
From our 20+ years of experience, we’ve seen countless transmission issues caused by improperly programmed modules. A generic, non-programmed TCM simply can’t account for the unique parameters of your Pontiac Montana. Our process involves loading the latest GM software tied directly to your VIN. This ensures the TCM knows exactly how to respond to engine load, vehicle speed, and driver input, protecting your transmission from premature wear and potential catastrophic failure. Investing in a properly programmed 2006-2009 Pontiac Montana Transmission Control Module is the smartest way to ensure a lasting repair.
Frequently Asked Questions
What does “VIN Programmed” actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and the latest GM-certified software onto the module before we ship it. This makes the module a perfect electronic match for your specific vehicle, allowing for a simple plug-and-play installation without any further programming needed.
Is this module difficult to install on my Pontiac Montana?
No, installation is straightforward for a DIYer with basic tools. On the 2006-2009 Montana, the TCM is typically located on the LH strut tower. The process usually takes under 30 minutes. Simply disconnect the battery, unplug the old module, install the new one, and reconnect the battery.
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 of a P0700, it’s always best to have the vehicle scanned for any other specific codes (e.g., P0751, P0756) to confirm the diagnosis. In most cases where the TCM itself is faulty, this part is the correct solution.
Do I need any special tools to complete the job?
Basic hand tools like a socket set are typically all that’s required to access and replace the module. We do recommend using a basic OBD2 scan tool to clear any stored codes from the vehicle’s memory after the installation is complete.
Is this the correct part for other GM vehicles?
Yes, this T42 TCM is compatible with a wide range of GM vehicles equipped with 4-speed automatic transmissions like the 4L60E and 4L65E. While this listing is for the 2006-2009 Pontiac Montana Transmission Control Module, it also fits many Chevrolet, GMC, Buick, and Saturn models. Please verify the part number or use our vehicle lookup tool to ensure proper fitment.
