Is Your Pontiac Pursuit’s Transmission Acting Up?
If you’re dealing with the frustration of a transmission that slams into gear, refuses to shift, or has your car stuck in limp mode, you’re not alone. The Transmission Control Module (TCM) is the electronic brain of your automatic transmission, and when it fails, it can cause a host of alarming and unsafe driving conditions. This OEM-quality T42 Transmission Control Module, part number 24239926, is the direct-fit, reliable solution for your 2006 Pursuit Transmission Control Module needs, arriving pre-programmed to your vehicle’s VIN for a hassle-free, plug-and-play installation.
From the Diagnostic Bay: The Case of the Confusing Cobalt
A few months back, a 2008 Chevy Cobalt came into my shop. The owner was frustrated; he’d already replaced two shift solenoids based on a P0750-range code, but the harsh 1-2 shift and intermittent ‘limp mode’ persisted. The check engine light was a constant annoyance. After hooking up my scan tool and seeing the communication errors, I suspected the TCM. In my 20+ years of experience, I’ve seen hundreds of these T42 modules fail due to internal circuit board issues caused by heat and vibration. We installed one of our VIN-programmed modules, and in less than 30 minutes, the car was shifting like it just left the factory. It’s a classic example of how chasing symptoms can be costly, while replacing the core electronic controller provides a definitive fix.
Telltale Signs of a Failing T42 TCM
A faulty TCM can mimic other transmission problems, so it’s crucial to know the signs. If your vehicle is experiencing any of the following, a failing module is a likely culprit:
- ✔ Harsh, jerky, or delayed gear shifts.
- ✔ The vehicle is stuck in a single gear (often 2nd or 3rd) and will not shift up or down.
- ✔ An illuminated Check Engine Light or Transmission Warning Light.
- ✔ Diagnostic Trouble Codes (DTCs) are present, especially P0700 (Transmission Control System Malfunction) or various solenoid-specific codes.
- ✔ A sudden drop in fuel economy or a transmission overheating warning.
- ✔ Complete loss of communication with the module, leading to total transmission failure.
A Straightforward Guide to DIY Installation
One of the biggest benefits of our pre-programmed module is that it eliminates the need for an expensive trip to the dealership. This is a job most DIYers can handle with basic tools in their own driveway.
- Safety First: Begin by disconnecting the negative terminal from your vehicle’s battery to prevent any electrical shorts and help reset the system.
- Locate the Module: On your 2006 Pontiac Pursuit, the TCM is located on the driver’s side of the engine bay, mounted to the LH strut tower.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount the new 2006 Pursuit Transmission Control Module in place and securely fasten it. Reconnect the electrical harnesses, ensuring they click into place.
- Final Steps: Reconnect the negative battery terminal. While the module is plug-and-play, it’s best practice to use a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory. Start the car and take it for a test drive to confirm smooth shifting.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This ensures it works correctly right out of the box, with no additional programming or calibration required.
What is a core charge? Do I need to send my old part back?
There is no core charge for this part. You can keep your old module, saving you the time and expense of return shipping.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. In many cases where the TCM itself has failed internally, replacing it with this module will resolve the P0700 code and any related solenoid codes.
What tools are needed for installation?
Installation typically only requires basic hand tools, such as a socket set to unbolt the module and disconnect the battery. No specialized electronic tools are necessary.
