Restore Smooth, Reliable Shifting to Your Family’s Minivan

Is your 2006-2007 Buick Terraza suffering from harsh shifting, delayed gear engagement, or a concerning check engine light? A faulty transmission control module (TCM) can disrupt your family’s routine and compromise safety on the road. This pre-programmed T42 Transmission Control Module is the definitive, hassle-free solution to restore your minivan’s smooth, factory-new performance and get you back on the road with confidence.

Common Symptoms & Your Solution

If you’re experiencing any of the following issues, a failing TCM is the likely culprit. This module is engineered to resolve these problems directly:

  • Abrupt, harsh, or erratic gear changes
  • The vehicle getting stuck in “limp mode” (usually 2nd or 3rd gear)
  • Illuminated Check Engine or Transmission warning lights
  • Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults
  • Failure to upshift or downshift properly
  • A noticeable decrease in fuel economy

Installing this professionally programmed 2006-2007 Buick Terraza transmission control module is the most effective way to permanently fix these issues, ensuring your vehicle operates safely and efficiently.

Frequently Asked Questions

Do I need to have this module programmed by a dealership?

No. This is the biggest benefit of our product. We pre-program the module to your vehicle’s VIN before shipping, so it’s ready for a plug-and-play installation right out of the box. No extra trips or fees are required.

Where is the TCM located on a 2006-2007 Buick Terraza?

On the Buick Terraza for these model years, the transmission control module is typically located on the driver’s side of the engine compartment, mounted to the LH strut tower.

Will this fix a P0700 trouble code?

Yes, in many cases it will. The P0700 code is a general fault code indicating the TCM has detected a problem. A failing TCM is one of the most common reasons for this code to appear, and replacing it with our programmed 2006-2007 Buick Terraza transmission control module often resolves the root cause.

What tools are required for installation?

Installation typically requires only basic hand tools, such as a socket set, to access and unbolt the module. We recommend disconnecting the battery before you begin. A scan tool can be helpful for clearing any stored codes after installation but is not always necessary.

Is there a core charge for my old part?

No, there is no core charge. You can keep your old part, which simplifies the process and saves you the hassle of a return shipment.
