Restore Smooth, Safe Shifting to Your Buick Terraza
Is your 2006-2007 Buick Terraza experiencing frustrating and unsafe transmission problems? Harsh shifting, getting stuck in gear, or a persistent check engine light can turn your reliable family minivan into a source of stress. A faulty Transmission Control Module (TCM) is often the culprit, disrupting communication between the engine and transmission. This pre-programmed T42 TCM is the definitive, plug-and-play solution to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Solution
If your van is exhibiting any of the following signs, it’s a strong indicator that you need a replacement 2006-2007 Buick Terraza transmission control module:
- Abrupt, harsh, or erratic gear changes
- Delayed engagement when shifting from Park to Drive or Reverse
- Vehicle stuck in “limp mode” (usually 2nd or 3rd gear)
- Illuminated Check Engine Light or Transmission Warning Light
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift, leading to poor acceleration and fuel economy
This module is engineered to resolve these issues directly. By arriving pre-programmed to your vehicle’s specific VIN, it ensures all software is up-to-date and perfectly matched to your Terraza’s factory settings, eliminating the need for an expensive trip to the dealership.
An Expert’s Note on VIN Programming
In modern vehicles like your Terraza, the TCM is more than just a simple controller; it’s the brain of the transmission. It constantly communicates with the Engine Control Module (ECM) and other sensors. VIN programming isn’t just a convenience—it’s critical. It loads the precise operational parameters and software updates specific to your van’s build. Installing a non-programmed module often leads to immediate compatibility errors, persistent shifting problems, and warning lights. Our process ensures that when you plug this unit in, it works correctly from the very first start.

Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that controls your automatic transmission. It reads data from various sensors to determine the perfect time to shift gears, control fluid pressure, and lock the torque converter, ensuring smooth operation and optimal fuel efficiency.
Do I need to program this module after I receive it?
No. We handle all the programming before it ships. This 2006-2007 Buick Terraza transmission control module is programmed using your vehicle’s VIN, making it a true plug-and-play part that is ready for immediate installation.
Where is the TCM located on my 2006-2007 Buick Terraza?
On the Buick Terraza and similar GM minivans of this era, the TCM is typically found in the engine compartment, mounted on the driver’s side (LH) strut tower. Always disconnect the battery before beginning the replacement.
Will this fix my check engine light for code P0700?
Yes, in most cases. Code P0700 is a general fault code indicating the TCM has detected a problem. If the TCM itself is the source of the failure, replacing it with this programmed unit will resolve the code and the underlying issue. We recommend clearing all codes with a scan tool after installation.
What happens if I don’t replace a failing TCM?
Continuing to drive with a bad TCM can lead to more severe transmission damage. Erratic fluid pressure and improper shifting can cause excessive wear on clutches and other internal components, potentially resulting in a much more expensive transmission rebuild down the road.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep or dispose of your old module without the hassle of returning it.
