If your 2006 Pontiac Pursuit is suffering from jerky shifts, getting stuck in gear, or has the check engine light on with transmission codes, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless GM vehicles sidelined by a faulty Transmission Control Module (TCM). The T42 module is the electronic brain of your automatic transmission, and when it fails, it can make your car feel unreliable and unsafe to drive. This isn’t just an inconvenience; it’s a critical failure that impacts everything from fuel economy to drivability.
This is a direct-replacement, OEM-quality T42 TCM, specifically part number 24241806. The most significant benefit we offer is our expert VIN programming service. Before this module ships, we flash it with your vehicle’s specific VIN and the latest GM software updates. This means it arrives at your door ready for a true plug-and-play installation, completely eliminating the need for a costly trip to the dealership for programming. You get a reliable fix that restores the smooth, predictable shifting you expect from your vehicle.
Is Your Pontiac Pursuit Showing These Telltale Signs?
A failing TCM often mimics other transmission problems, but there are specific symptoms I look for during diagnosis. If you’re experiencing any of the following, a faulty 2006 Pursuit Transmission Module is a likely culprit:
- âś” Harsh, slamming, or erratic gear changes.
- âś” The vehicle feels stuck in one gear (often called “limp mode”).
- âś” Delayed engagement when shifting from Park to Drive or Reverse.
- âś” Check Engine Light illuminated with Diagnostic Trouble Codes (DTCs) such as P0700, P0750-P0758 (solenoid circuit faults), or other transmission-related codes.
- âś” A sudden drop in fuel efficiency.
- âś” The transmission seems to slip out of gear while driving.
Case Study: A Tricky Diagnosis
I once had a 2008 Chevy HHR come into the shop with a P0752 code, indicating a “Shift Solenoid A Stuck On” fault. The owner had already replaced the solenoid twice at another shop, but the problem persisted. After a quick data stream analysis, I noticed the command signals from the TCM were erratic. The solenoid was doing its job, but the TCM was giving it bad orders. We installed one of our VIN-programmed T42 modules, cleared the codes, and the car shifted perfectly. It’s a classic example of how a bad TCM can send you chasing mechanical ghosts, costing you time and money. This part fixes the root cause.
DIY Installation: Your Pursuit’s Transmission Fixed in Under 30 Minutes
One of the best parts about this solution is how accessible it is for the DIY mechanic. You don’t need a lift or specialized transmission tools. For your 2006 Pursuit, the TCM is located in a very accessible spot. Follow these steps for a smooth installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and help reset the system.
- Locate the Module: On the Pontiac Pursuit, the TCM is typically found on the driver’s side, mounted to the LH strut tower in the engine bay.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. You should hear a click as they lock in.
- Final Steps: Reconnect the battery terminal. While our programming resolves most issues, it’s always 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 the shifting issues are resolved.

Frequently Asked Questions
What does “VIN Programmed” actually mean?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM-certified software directly onto the module before we ship it. This ensures it communicates perfectly with your car’s engine computer and other systems, just like an original part from the factory, without needing dealer tools.
Do I need to send my old TCM back?
No, there is absolutely no core charge or need to return your old part. You can dispose of it or keep it, saving you the hassle and cost of return shipping.
Will this fix a P0700 trouble code?
A P0700 is a generic code indicating the TCM has detected a fault. Often, when the TCM itself is the source of the problem, replacing it with this pre-programmed unit will resolve the P0700 and any other related transmission codes.
Is this a difficult part for a beginner to install?
Not at all. For the Pursuit and similar models, the TCM is in a very accessible location in the engine bay. With basic hand tools and our instructions, most DIYers can complete the job in under 30 minutes. The key is our pre-programming, which removes the most difficult, software-related step.
What kind of warranty is included?
We stand behind our parts with a full one-year warranty. We build these modules to meet or exceed OEM standards for reliability, ensuring you get a lasting solution for your transmission problems.
