Restore Peak Transmission Performance in Your GM Vehicle
Are you experiencing frustrating and unpredictable shifting issues with your 2006 Pontiac Pursuit or another compatible GM vehicle? A faulty Transmission Control Module (TCM) is often the culprit behind problems that can seem like a major mechanical failure. This genuine quality T42 TCM, part number 24239926, is the definitive solution to restore the smooth, reliable performance your vehicle had when it was new. As the electronic brain of your automatic transmission, the TCM is responsible for managing shift points, torque converter clutch engagement, and fluid pressure. When it fails, the symptoms can range from merely annoying to completely disabling. This replacement module arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2008 Chevy Silverado come in with what the owner described as a “completely shot transmission.” It was banging into gear, refusing to upshift past 3rd, and the dash was lit up with warnings. He was convinced he needed a full transmission rebuild, a multi-thousand dollar job. After plugging in our scan tool, we saw a cascade of solenoid communication errors. Instead of tearing down the transmission, we checked the TCM. Sure enough, it was failing intermittently. We installed a VIN-programmed T42 module, cleared the codes, and took it for a test drive. The truck shifted perfectly, like it just rolled off the factory floor. A 30-minute fix saved the customer thousands and solved a problem that looked catastrophic.
Symptoms of a Failing T42 TCM
- ✔ Hard, jerky, or erratic gear shifts that disrupt your drive.
- ✔ The vehicle gets stuck in a single gear, often called “limp mode,” as a protective measure.
- ✔ Your check engine light or transmission warning light is illuminated on the dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ Delayed or no engagement when shifting from Park to Drive or Reverse.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting.
- ✔ Inability to shift up or down, or random downshifting while driving.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the TCM. This is crucial because every vehicle has slight differences. Programming ensures the module works perfectly with your engine, tire size, and gear ratios for optimal performance and fuel efficiency. Our service saves you a trip to the dealership for this mandatory step.
Is this a difficult part to install myself?
For most DIY mechanics with basic tools, the installation is straightforward and typically takes less than 30 minutes. The TCM is usually located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. No complex procedures are required.
Will this part fix my specific transmission problem?
This TCM is a direct solution for issues caused by a faulty electronic control module. If your vehicle displays symptoms like erratic shifting, limp mode, or specific TCM-related error codes (e.g., P0700), this part is very likely the solution. It addresses the electronic brain, not internal mechanical failures like a broken clutch or gear.
Do I need to send my old part back (core charge)?
No, there is absolutely no core charge for this part. You can keep your old module or dispose of it at your convenience, making the process simpler and more cost-effective for you.
What vehicles is this T42 TCM compatible with?
This module fits a wide array of 2006-2014 General Motors vehicles equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E. This includes popular models such as the Chevrolet Silverado, Tahoe, Impala, Cobalt; GMC Sierra, Yukon; Buick LaCrosse; Cadillac DTS; Pontiac G6; and Saturn Vue, among many others.
