Restore Peak Transmission Performance in Your Chevrolet SSR
Is your 2005-2006 Chevrolet SSR suffering from erratic shifting, getting stuck in gear, or displaying a check engine light? These are classic signs of a failing Transmission Control Module (TCM), the electronic brain responsible for managing your vehicle’s automatic transmission. A faulty TCM can turn your unique sport truck into a source of frustration. This genuine GM T42 Transmission Control Module, service part number 24239926, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a seamless, plug-and-play installation.
The TCM is a critical component that orchestrates every aspect of your transmission’s operation, from gear changes and torque converter lockup to line pressure. When it begins to fail due to heat, vibration, or age, the communication between your engine and transmission breaks down, leading to poor performance, decreased fuel economy, and potentially severe transmission damage if left unaddressed. Our VIN programming service ensures this replacement module has the latest factory software for your exact vehicle, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a customer with a 2006 Trailblazer SS—which shares a similar powertrain to the SSR—that was driving him crazy. It would shift perfectly when cold, but after 20 minutes of driving, it would slam into gear and occasionally get stuck in 3rd. He had already replaced two shift solenoids with no luck. The scanner showed intermittent solenoid circuit codes that didn’t make sense. We suspected the TCM was failing under heat. We installed one of our VIN-programmed T42 modules, and the problem was solved instantly. It wasn’t a mechanical issue at all; it was the computer giving faulty commands. This is a perfect example of how a pre-programmed 2005-2006 SSR TCM can save you time and money on unnecessary repairs.
Symptoms of a Failing GM T42 TCM
If you’re experiencing any of the following issues, a failing TCM is the likely culprit. Replacing it can restore the smooth, responsive shifting you expect from your vehicle.
- ✔ Harsh, erratic, or delayed gear shifts.
- ✔ The vehicle enters “limp mode,” often stuck in 2nd or 3rd gear.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, or other solenoid-related codes.
- ✔ Inability to upshift or downshift properly.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ The transmission seems to be overheating more than usual.

- Safety First: Always disconnect the negative battery terminal before beginning work.
- Locate and Remove: Find the module on the front LH frame. Carefully disconnect the electrical connectors and unbolt the module from its bracket.
- Install New Module: Bolt the new, pre-programmed module into place and securely reconnect the electrical harnesses.
- Reconnect Battery: Reattach the negative battery terminal.
- Final Steps: While the module is plug-and-play, it’s good practice to use a scan tool to clear any stored DTCs from the vehicle’s memory after installation.
Frequently Asked Questions
What does a Transmission Control Module (TCM) do on my SSR?
The TCM is a computer that acts as the brain for your automatic transmission. It receives data from various sensors on the engine and transmission to control shift timing, fluid pressure, and torque converter lockup, ensuring smooth and efficient operation.
What does “VIN Programmed” mean and why is it important?
“VIN Programmed” means we flash the module with the specific software and calibration file for your vehicle’s unique Vehicle Identification Number (VIN). This is critical for ensuring the TCM works correctly with your SSR’s specific engine, tire size, and gear ratios, and avoids compatibility issues that require a dealership visit.
Is this TCM difficult to install?
For the 2005-2006 SSR, the TCM is located on the front LH frame, making it reasonably accessible. With basic hand tools, the physical replacement typically takes under an hour. Since our modules are pre-programmed, no complex computer work is needed after installation.
Will this part fix a P0700 diagnostic 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 can resolve the root cause of the P0700, it’s important to scan for other transmission-specific codes (like P07xx) to confirm the TCM is the issue.
Do I need to return my old TCM?
No. We do not require you to return your old part. There is no core charge associated with this purchase, saving you time and return shipping costs.
