If you’re dealing with the frustration of a transmission that won’t shift correctly, gets stuck in gear, or triggers a check engine light, you’ve come to the right place. As a technician with over two decades of experience, I know that for many GM vehicles from this era, the T42 Transmission Control Module (TCM) is often the culprit. This isn’t just a replacement part; it’s a direct solution to restore the crisp, reliable shifting your 2006 Pontiac Pursuit was built to deliver.
This module is the brain of your automatic transmission, managing everything from shift points to torque converter lockup. When it fails, the symptoms can range from annoying to dangerous. Our replacement 2006 Pursuit Transmission Control Module comes expertly pre-programmed to your vehicle’s specific VIN, making it a true plug-and-play fix that eliminates the need for an expensive trip to the dealership for programming.
A Technician’s Notebook
I remember a 2007 Pontiac G6—a close relative to the Pursuit—that came into the shop with a classic case of intermittent transmission failure. The owner was fed up. Some days it drove perfectly, others it would slam into gear or refuse to upshift. The codes were generic, mostly a P0700 (Transmission Control System Malfunction). After checking the wiring and solenoids, which all tested fine, we honed in on the TCM. The internal electronics had started to break down from heat and vibration. Swapping in a VIN-programmed T42 module like this one solved the problem instantly. The customer was back on the road in under an hour, no more guesswork or anxiety.
Is Your Pontiac Exhibiting These Transmission Woes?
- ✔ Harsh, erratic, or delayed gear shifts that make driving unpredictable.
- ✔ The vehicle is stuck in “limp mode,” often refusing to shift out of 2nd or 3rd gear.
- ✔ Your check engine light or transmission warning light is on, with Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- ✔ A sudden drop in fuel efficiency or a transmission that seems to be overheating.
- ✔ Complete loss of communication with the transmission module, preventing shifts altogether.
A Straightforward Guide to Installation
For the 2006 Pontiac Pursuit, this job is well within reach for a DIYer. You’ll find the TCM located at the driver’s side strut tower in the engine bay. The entire process should take less than 30 minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before you begin. This prevents electrical shorts and helps reset the vehicle’s computer systems.
- Locate the Module: Open the hood and find the TCM mounted on the driver’s side (LH) strut tower.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs, so be gentle. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new 2006 Pursuit Transmission Control Module into place and securely reconnect the electrical harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While our VIN programming handles the critical setup, it’s good practice to use a basic OBD2 scan tool to clear any stored fault codes from the system. Start the vehicle and enjoy smooth shifting!

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean for me?
It means we load your car’s specific Vehicle Identification Number (VIN) and the latest GM software onto the module before we ship it. This ensures it communicates perfectly with your car’s engine computer and other systems right out of the box, with no extra programming required.
Do I need any special tools for this installation?
No special tools are needed. Basic hand tools, such as a socket set to remove the mounting bolts and your hands to undo the connectors, are all that’s required for this straightforward job.
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 (like internal failure), it’s important to ensure there are no other issues like bad wiring or faulty solenoids. In my experience, a faulty TCM is the most common cause for this code on these vehicles.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module or dispose of it without the hassle of returning it, saving you time and money.
