Is Your Transmission Acting Up? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle that won’t shift correctly. The hesitation, the harsh clunking between gears, or being stuck in ‘limp mode’ can turn any drive into a stressful ordeal. If your Pontiac Pursuit or other GM vehicle is experiencing these issues, a failing Transmission Control Module (TCM) is the most likely culprit. This VIN-programmed T42 Transmission Control Module is the definitive solution, designed to restore your vehicle’s performance and your peace of mind without an expensive trip to the dealership.
Common Symptoms & Your Solution
A faulty TCM can manifest in numerous ways, disrupting your vehicle’s drivability and safety. This module is engineered to resolve these exact problems, getting you back to smooth, predictable operation. If you’re experiencing any of the following, it’s time for a replacement:
- Harsh, erratic, or delayed gear shifts
- Vehicle is stuck in one gear (limp mode)
- Check Engine Light or Transmission Warning Light is on
- Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related codes are present
- Complete failure to upshift or downshift
- Noticeably poor fuel economy

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles, the TCM isn’t just a simple controller; it’s a networked computer that’s integral to the vehicle’s entire powertrain system. It constantly communicates with the Engine Control Module (ECM) and other sensors. VIN programming loads the exact software and calibration files your specific vehicle model, year, and option package requires. Skipping this step with a generic, unprogrammed module is a recipe for failure—it can lead to persistent shifting problems, incorrect performance, and even damage to your transmission. Our pre-programming service ensures this Programmed T42 Transmission Control Module works perfectly right out of the box.
Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is the ‘brain’ of your automatic transmission. It uses data from various sensors to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smooth operation.
Is this module truly ‘plug-and-play’?
Yes. Because we program the module to your vehicle’s specific VIN before shipping, it is ready for installation immediately. No further programming or ‘flashing’ at a dealership is required, saving you significant time and money.
How do I know for sure that my TCM is the problem?
While the symptoms listed above are strong indicators, a professional diagnosis using a high-quality scan tool is the best way to confirm. Common TCM-related fault codes (like P0700) are a clear sign that the module needs replacement.
Will installing this clear my check engine light?
This module will resolve the underlying electronic fault that caused the check engine light to illuminate. After installation, you will need to clear the stored codes using a standard OBD-II scan tool, and the light should remain off.
Do I need to send my old part back?
No. We do not require a core charge for this Programmed T42 Transmission Control Module. You can keep or dispose of your old part at your convenience.
Where is the TCM located on my vehicle?
Location varies by model. Common locations include the engine compartment on the driver or passenger side, next to the battery, or under the air cleaner box. The included fitment list provides specific locations for many compatible vehicles.
