If your 2006 Pontiac Pursuit is suffering from harsh shifts, getting stuck in gear, or throwing transmission codes, you’ve likely pinpointed the problem: a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen these T42 modules cause countless headaches. This replacement 2006 Pursuit Transmission Module is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair that gets you back on the road without a costly trip to the dealership.
The TCM is the brain of your automatic transmission, responsible for every gear change, torque converter lockup, and line pressure adjustment. When it fails, the symptoms can range from annoying to dangerous. This module restores the precise communication needed for your 4-speed automatic transmission (like the 4L60E family) to operate as the factory intended, ensuring smooth, predictable performance and restoring your car’s drivability.
Is Your Pursuit Showing These Telltale Signs?
A faulty TCM can manifest in several ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Check Engine Light or Transmission Warning Light is illuminated, often with Diagnostic Trouble Codes (DTCs) like P0700 (Transmission Control System Malfunction), P0750, P0753, P0758, or other solenoid-related faults.
- ✔ Harsh, erratic, or delayed shifting that makes driving uncomfortable.
- ✔ The vehicle enters “limp mode,” getting stuck in a single gear (usually 2nd or 3rd) to protect the transmission from further damage.
- ✔ Complete loss of upshifting or downshifting capabilities.
- ✔ A noticeable drop in fuel economy as the transmission operates inefficiently.
- ✔ Intermittent electrical faults or a complete loss of communication with the module.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2006 Pontiac G5—which shares its platform and TCM with the Pursuit—that came into my shop with a baffling issue. The owner complained of random, violent downshifts on the highway. We checked the fluid, scanned for codes, and initially found nothing concrete. The problem was intermittent. After data-logging a drive, we saw the TCM command erratic line pressures just before the event. It wasn’t a solenoid or a sensor; the module itself was failing internally under thermal load. Replacing the TCM with a VIN-programmed unit like this one solved the problem instantly. It’s a classic failure mode for these T42 modules, and this part is the direct fix.
DIY Guide: Install Your TCM in Under 30 Minutes
Replacing the 2006 Pursuit Transmission Module is a straightforward job for any DIY enthusiast. No special tools are required, and since it comes pre-programmed, you avoid the hassle of dealer-level software flashing.
- Safety First: Disconnect the negative terminal from your car’s battery to prevent electrical shorts and help reset the vehicle’s electronic systems.
- Locate the Module: On your 2006 Pursuit, the TCM is typically located on the driver’s side, mounted to the strut tower in the engine bay.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Reconnect the electrical harnesses, ensuring they click securely into place.
- Final Steps: Reconnect the negative battery terminal. While the system may reset, it’s best practice to use a basic OBD-II scan tool to clear any stored DTCs from the system’s memory. Start the vehicle and test drive to confirm smooth shifting.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for my 2006 Pursuit?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software onto the module before shipping. This ensures it communicates perfectly with your car’s engine computer and other systems right out of the box, eliminating the need for dealer programming.
Do I need any special tools for this installation?
No. Basic hand tools, like a socket set to remove the mounting bolts and disconnect the battery, are all that’s required. An OBD-II scanner is recommended for clearing codes but is not always necessary.
Will this fix a P0700 code?
A P0700 code is a generic fault code indicating the TCM has detected a problem. While this module often resolves the root cause (like a failed internal driver that triggers other codes), you should always diagnose any specific solenoid or sensor codes that accompany it. In many cases, a faulty TCM is the primary culprit.
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.
How is this different from a part from the junkyard?
A junkyard part is not programmed to your car’s VIN and carries the same risk of failure as your old one. Our module is tested, loaded with fresh software specific to your vehicle for reliable performance, and backed by a one-year warranty.
