If your 2006 Pontiac Pursuit is suffering from erratic shifting, getting stuck in gear, or has an illuminated check engine light, you’re likely dealing with a failed Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen firsthand how a faulty T42 module can sideline an otherwise reliable vehicle. This direct-fit replacement, part number 24235753, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
This isn’t just a part; it’s a complete fix. The TCM is the brain of your automatic transmission, controlling everything from shift points to torque converter lockup. When it fails, communication between the engine and transmission breaks down, leading to the frustrating and potentially damaging symptoms you’re experiencing. Our 2006 Pursuit Transmission Module restores that critical link, ensuring your 4-speed automatic transmission operates with the precision and smoothness it had from the factory. Forget about costly dealership visits for programming—we handle that for you, so you can get back on the road quickly and confidently.
From the Diagnostic Bay: The Intermittent Limp Mode Mystery
A customer brought in a 2008 Chevy Cobalt—a cousin to the Pursuit with the same T42 TCM—with a complaint that drove them crazy. It would randomly drop into limp mode (stuck in 2nd gear) but would reset after shutting the car off. No consistent codes, just a general P0700 (Transmission Control System Malfunction) stored. We checked wiring and solenoids, which all tested fine. The culprit? The original TCM was failing internally due to heat cycles. We installed one of our VIN-programmed T42 modules, and the problem was solved in under 30 minutes. This is a classic failure I’ve diagnosed hundreds of times, and a pre-programmed module is the most efficient and reliable fix for both shops and DIYers.
Is Your Pontiac Showing These Symptoms?
- âś” Harsh, delayed, or unpredictable gear shifts.
- âś” Vehicle is stuck in “limp mode,” often in 2nd or 3rd gear.
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Diagnostic Trouble Codes (DTCs) such as P0700, P0750, P0753, P0758, or other solenoid-related faults are present.
- âś” Failure to upshift or downshift properly, leading to poor acceleration.
- âś” A noticeable decrease in fuel economy.
- âś” Complete loss of communication with the transmission module.
DIY-Friendly Installation Guide
- âś” Safety First: Park on a level surface and disconnect the negative terminal from your vehicle’s battery. This prevents electrical shorts and helps reset the system.
- âś” Locate the TCM: On your 2006 Pursuit, the TCM is typically located on the LH (driver’s side) strut tower in the engine compartment.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- âś” Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical connectors. Ensure they click into place.
- âś” Final Steps: Reconnect the battery terminal. Start the vehicle and let it idle for a few minutes. If you have a basic scan tool, it’s good practice to clear any lingering fault codes.
