Restore Peak Performance to Your Pontiac Pursuit’s Transmission
Is your 2006 Pontiac Pursuit suffering from erratic shifting, getting stuck in gear, or displaying a check engine light with transmission codes? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change, managing torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can cause a cascade of frustrating and potentially damaging issues. This replacement T42 TCM, service number 24243921, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We recently had a 2006 Pontiac G6 (which shares the same platform as the Pursuit) come into the shop. The owner had already replaced two shift solenoids trying to chase down a persistent P0752 code and harsh 1-2 shift. The problem would disappear for a day and then return. After hooking up our diagnostic tools, we saw that the command signals from the TCM were intermittent. The solenoids were fine; the module itself was the culprit. Installing a VIN-programmed T42 TCM like this one solved the problem instantly. It’s a reminder that troubleshooting should always start with the brain—the control module—before replacing components it commands.
Diagnosing and Solving with a 2006 Pursuit Transmission Module
A faulty TCM doesn’t just affect comfort; it impacts fuel economy, transmission longevity, and overall vehicle safety. Ignoring the symptoms can lead to more severe mechanical damage inside the transmission. This module is specifically designed to address these issues head-on. Because it arrives pre-programmed to your vehicle’s unique Vehicle Identification Number (VIN), it’s a true plug-and-play solution. There’s no need for an expensive trip to the dealership for programming. Simply install the module, and it will communicate seamlessly with your vehicle’s engine control module (ECM) and other systems, using the latest GM software updates for optimal performance.
Common Symptoms of a Failing T42 TCM
- ✔ Harsh, delayed, or erratic gear shifts that make driving uncomfortable.
- ✔ The vehicle enters “limp mode,” often getting stuck in 2nd or 3rd gear to prevent further damage.
- ✔ Illumination of the Check Engine Light or Transmission Warning Light on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) are stored, such as the general P0700 code or specific solenoid circuit codes (e.g., P0750, P0751, P0752).
- ✔ Complete failure to upshift or downshift, leaving you stuck in a single gear.
- ✔ Noticeably decreased fuel efficiency as the transmission operates inefficiently.
- ✔ The transmission may seem to slip between gears or fail to engage properly from a stop.
Installation and Compatibility
Replacing the 2006 Pursuit Transmission Module is a straightforward process for a DIY mechanic or a professional technician. On the Pursuit, the TCM is typically located on the driver’s side, attached to the strut tower in the engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one in its place. Once the new module is connected and the battery is reconnected, the vehicle is ready to go. While many codes will clear upon battery disconnection, it’s always best practice to use a scan tool to clear any remaining DTCs. This module is a direct replacement for a wide range of GM part numbers, including 24252114, 24234503, 24230461, and many others, ensuring broad compatibility across dozens of GM models from 2006-2014.
Frequently Asked Questions
What exactly does a Transmission Control Module do?
The TCM is a computer that processes data from various sensors on your vehicle’s engine and transmission. It uses this information to control shift points, line pressure, and torque converter clutch operation to provide smooth shifting and optimal fuel economy.
Why is VIN programming essential for this part?
VIN programming loads your vehicle’s specific software and calibrations onto the module. This ensures it communicates correctly with the Engine Control Module (ECM) and other vehicle systems. Without it, the transmission may not shift correctly, or the vehicle may not start at all.
Can I install this module myself?
Yes, installation is generally simple for those with basic mechanical skills. It’s typically located in the engine bay and requires only basic hand tools to replace. Since our modules come pre-programmed, you avoid the need for specialized dealer tools.
Will this replacement module fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the check engine light be turned on. While this module often resolves the root cause that triggers a P0700, it’s important to have the specific transmission codes (e.g., P07xx) read to confirm the diagnosis.
Is there a core charge for this part?
No, there is no core charge required for this transmission control module. You can keep your old part without needing to send it back, saving you time and hassle.
