This OEM-quality T42 TCM, part number 24240449, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
Forget expensive dealership visits and the hassle of programming. We handle the complex part for you. By programming this module with the latest GM software updates specific to your SSR, we ensure it communicates flawlessly with your vehicle’s systems right out of the box. This restores precise shift points, proper torque converter lockup, and accurate diagnostic reporting, getting your unique truck back on the road with the smooth performance you expect.
Common Signs of a Failing GM T42 TCM
- âś” Harsh, delayed, or unpredictable gear shifts.
- âś” The vehicle is stuck in “limp mode,” often in 2nd or 3rd gear.
- âś” Check Engine Light or Transmission Warning Light is illuminated.
- âś” Diagnostic Trouble Codes (DTCs) are present, such as the general P0700 code or specific solenoid codes like P0751, P0756, etc.
- âś” A complete loss of shifting ability or failure to engage gears.
- âś” Noticeably poor fuel mileage and a feeling of sluggish acceleration.
Case Study: A Tricky Diagnosis
I had a 2006 SSR roll into my shop last month with a frustrating, intermittent issue. The owner complained it would randomly refuse to shift out of 2nd gear after driving for about 20 minutes, but no codes were stored initially. After a long test drive with a high-end scan tool, I finally caught it in the act—a U0101 (Lost Communication with TCM) code popped up just as it went into limp mode. The wiring and connectors were perfect. It was classic heat-related failure inside the TCM. We installed one of our pre-programmed T42 modules, and the problem was solved in under an hour, saving the customer a tow to the dealer and days of waiting.
Your Direct Installation Guide
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic component replacement.
- âś” Locate the Module: On the 2005-2006 SSR, the TCM is typically located on the front left-hand (driver’s side) frame rail.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as old plastic can be brittle. Once disconnected, unbolt the module from its mounting bracket.
- âś” Install the New TCM: Mount the new, pre-programmed module in the same location and securely fasten it. Reconnect the electrical harnesses, ensuring they click into place.
- âś” Final Steps: Reconnect the battery terminal. While our programming resolves most issues, it’s good practice to use a basic OBD2 scanner to clear any old, stored fault codes from the vehicle’s memory. Start the vehicle and test drive to confirm smooth shifting.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. This Transmission Control Module comes fully programmed to your vehicle’s VIN number. It is ready for installation right out of the box, with no additional programming required.
What is a T42 TCM?
The T42 is the specific hardware platform used by General Motors for the Transmission Control Module in a wide range of vehicles, primarily those with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem and requested the Check Engine Light be turned on. While this module often resolves the root cause (like an internal TCM failure), you should scan for other ‘P’ codes to confirm the specific issue. If the TCM itself is the source of the fault, this part is the correct fix.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module, which saves you the time and expense of shipping it back.
