Restore Smooth Shifting to Your Pontiac Pursuit
If you’re dealing with the headaches of a faulty transmission in your 2006 Pontiac Pursuit—like harsh gear changes, getting stuck in limp mode, or a persistent check engine light—you’ve come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Transmission Control Module (TCM) can make a reliable car feel unpredictable. This T42 TCM, corresponding to part number 24238856, is the definitive solution to restore your vehicle’s performance and your peace of mind.
The TCM is the brain of your automatic transmission, responsible for orchestrating every shift, managing torque converter lockup, and monitoring system health. When it fails, the symptoms can range from annoying to dangerous. This replacement module is meticulously prepared to OEM specifications and, most importantly, comes pre-programmed to your vehicle’s specific VIN. This means you can skip the expensive trip to the dealership for programming; it’s a true plug-and-play fix that gets you back on the road quickly and confidently.
Case Study: A Tricky Diagnosis
I remember a 2007 Pontiac G6 that came into my shop. The owner was frustrated—the car would randomly refuse to shift past 2nd gear, and the check engine light was on with a generic P0700 code. Another shop had already replaced a shift solenoid with no success. After a quick scan, I noted intermittent communication loss with the TCM. Instead of throwing more parts at it, we tested the module’s power and ground circuits, which were fine. The issue was internal to the TCM itself, a common failure point due to heat cycles and vibration. Installing a VIN-programmed T42 module like this one solved the problem in under 30 minutes. The customer was thrilled to have their car back, shifting perfectly, without the dealership hassle.
Is Your Pontiac Showing These Signs?
A failing TCM often gives clear warning signs. If you’re experiencing any of the following, it’s a strong indicator that your module needs attention. Addressing it with a reliable 2006 Pursuit TCM can prevent further damage to your transmission.
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- ✔ The vehicle is stuck in a single gear (often called “limp mode”) to protect the transmission.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) are stored, such as P0700 (Transmission Control System Malfunction), P0750-P0758 (Shift Solenoid errors), or other transmission-related codes.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting.
- ✔ Complete loss of communication with the TCM, preventing diagnostics.
A Straightforward Guide to Installation
One of the best features of this module is its simple installation. For a 2006 Pontiac Pursuit, you can typically complete the job in your own driveway with basic hand tools. No complex programming is needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: On your Pursuit, the TCM is typically found on the driver’s side, attached to the LH strut tower in the engine bay. It’s a silver box with electrical connectors.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. Then, unbolt the module from its mounting bracket. Keep track of the hardware.
- Install the New Module: Mount the new, VIN-programmed TCM in the same location and securely tighten the bolts. Reconnect the wiring harnesses, ensuring they click into place.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and let it idle for a few minutes. If you have a basic OBD2 scan tool, it’s good practice to clear any lingering fault codes from the ECU.

Do I need to take this part to a dealer for programming?
Do I need to take this part to a dealer for programming?
No. This Transmission Control Module is delivered pre-programmed to your vehicle’s VIN. This allows for a direct, plug-and-play installation without requiring any additional programming from a dealership or mechanic, saving you time and money.
What tools do I need for installation?
Installation typically requires only basic hand tools, such as a socket set and ratchet to remove the mounting bolts and a flathead screwdriver to help unclip the electrical connectors if they are tight. No specialized diagnostic equipment is needed for the installation itself.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a faulty TCM is a very common cause, this code can also be triggered by other transmission issues. However, if you are also experiencing symptoms like erratic shifting or limp mode, replacing the TCM is the most likely solution.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep your old module without the hassle of returning it, making the repair process simpler and more convenient.
