If your 2006 Pontiac Pursuit is suffering from harsh shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is often the culprit. As the electronic brain of your automatic transmission, the TCM is responsible for every gear change. Over time, heat and vibrations can cause internal components to fail, leading to the frustrating and sometimes dangerous driving symptoms you’re experiencing. This is a direct-replacement T42 TCM, part number 24234274, designed to restore your vehicle’s original performance and reliability.
Over my two decades in the garage, I’ve seen countless drivers worry about needing a complete transmission rebuild when the real issue was a faulty module. Before you authorize an expensive, time-consuming repair, consider this cost-effective and dependable solution. We solve the biggest hurdle for you: this module arrives at your door pre-programmed to your vehicle’s specific VIN. This means no expensive trips to the dealership for programming—it’s a true plug-and-play fix that you or your mechanic can install quickly, getting you back on the road with confidence.
From the Diagnostic Bay: A Costly Mistake Avoided
A customer brought in their Chevy HHR with classic signs of transmission failure: banging into gear and refusing to shift past 2nd. Another shop had quoted them over $2,500 for a transmission overhaul. I hooked up my scanner and found a P0752 code (Shift Solenoid ‘A’ Stuck On). While this can be a solenoid issue, experience told me to check the TCM first. The T42 modules on these platforms are notorious for failing. We swapped in a VIN-programmed module, cleared the codes, and the HHR shifted like new. The customer saved thousands, all because we diagnosed the brain, not just the body, of the transmission.
Is Your Pontiac Exhibiting These Telltale Signs?
A failing TCM will give you clear warnings. If you’re noticing any of the following, it’s time to inspect your module.
- âś” Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- âś” Vehicle is stuck in “limp mode,” often only using 2nd or 3rd gear.
- âś” Check Engine Light or Transmission Warning Light is on, with Diagnostic Trouble Codes (DTCs) like P0700, P0750, P0751, or other solenoid-related faults.
- âś” Complete loss of upshifting or downshifting capabilities.
- âś” A noticeable drop in fuel economy or signs of the transmission overheating.
- âś” Intermittent communication loss with the module, causing unpredictable performance.
Your 30-Minute Path to Smoother Shifts
Replacing the 2006 Pursuit Transmission Module is a straightforward job for any DIY enthusiast or professional. No specialized tools are required.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic work.
- Locate the Module: On your Pontiac Pursuit, the TCM is typically found on the driver’s side, attached to the LH strut tower in the engine bay.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, VIN-programmed TCM into place and securely reconnect the wiring harnesses. Ensure the clips click into place.
- Final Steps: Reconnect the battery terminal. While the module is pre-programmed, it’s good practice to use a basic OBD2 scan tool to clear any stored fault codes from the ECU.
