If your 2006 Pontiac Pursuit is suffering from erratic shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen how a faulty TCM can sideline an otherwise perfectly good vehicle. This T42 Transmission Control Module, part number 24256960, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
The TCM is the brain of your automatic transmission, controlling everything from shift points to torque converter lockup. When it fails, communication breaks down, leading to the frustrating and sometimes unsafe driving conditions you’re experiencing. Our module restores that crucial link, ensuring your transmission operates exactly as the manufacturer intended, without requiring an expensive trip to the dealership for programming.
Is Your Pontiac Exhibiting These Telltale Signs?
- âś” Harsh, jerky, or delayed gear shifts.
- âś” Vehicle is stuck in “limp mode” and won’t shift out of a single gear (often 2nd or 3rd).
- âś” Check Engine Light or Transmission Warning Light is on with Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- âś” Complete failure to upshift or downshift, leading to poor acceleration and fuel economy.
- âś” Intermittent loss of communication with the module, causing unpredictable performance.
From the Diagnostic Bay
I remember a 2007 Pontiac G6—which uses the same T42 TCM as the Pursuit—that came into my shop stuck in third gear. The owner was quoted over a thousand dollars for a transmission rebuild at another shop. I hooked up my scan tool and found a P0700 code, which is a general transmission fault request. Digging deeper, I saw codes for multiple shift solenoids. Experience told me it’s rare for all solenoids to fail at once. The real issue was the TCM itself. We installed one of these VIN-programmed modules, and in under 30 minutes, the car was shifting perfectly. It saved the customer a massive, unnecessary repair bill.
Your Step-by-Step Installation Guide
Installing your 2006 Pursuit Transmission Module is a straightforward job for any DIY enthusiast. For the Pursuit, the TCM is conveniently located on the driver’s side strut tower in the engine compartment.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s adaptive memory.
- Locate the Module: Open the hood and find the TCM mounted to the driver’s side (LH) strut tower. It’s a silver box with electrical connectors.
- Disconnect and Remove: Carefully unclip the electrical harnesses. Then, unbolt the module from its mounting bracket. Keep the hardware safe.
- Install the New Module: Mount your new, pre-programmed TCM using the original hardware. Reconnect the electrical harnesses, ensuring they click securely into place.
- Final Steps: Reconnect the battery terminal. Start the vehicle and let it idle for a few minutes. While the module is plug-and-play, it’s good practice to use a basic scan tool to clear any stored historical fault codes.

Frequently Asked Questions
Do I need to take my car to the dealer after installation?
No. This module is delivered fully programmed to your vehicle’s VIN. It is a true plug-and-play solution, saving you hundreds in dealership programming fees.
What tools are required for the installation?
For a 2006 Pontiac Pursuit, you will typically only need basic hand tools, such as a socket set to remove the mounting bolts and a wrench for the battery terminal. No special diagnostic equipment is required.
Will this fix a P0700 trouble code?
