Restore Peak Performance to Your Chevrolet SSR
If you’re experiencing erratic shifting, a check engine light, or your 2005-2006 Chevrolet SSR is stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. As a seasoned technician, I’ve seen countless drivers frustrated by these exact issues, often fearing a costly transmission rebuild. The TCM is the electronic brain of your automatic transmission, responsible for every gear change and torque converter operation. When it fails, the symptoms can be dramatic, but the solution is often surprisingly straightforward.
This OEM-quality T42 TCM, part number 24243901, is the definitive fix for your transmission woes. We take the guesswork and high dealership costs out of the equation by pre-programming the module to your vehicle’s specific VIN. This ensures that once installed, it communicates flawlessly with your SSR’s other systems, restoring the smooth, predictable performance you expect. Don’t let a faulty module sideline your unique truck—get the right part, programmed and ready to install, right out of the box.
Case Study: A Tricky Diagnosis
A customer brought in his 2006 SSR with a classic complaint: harsh 1-2 shifts and occasionally getting stuck in 3rd gear. He’d already been to another shop that quoted him for a full transmission overhaul, a multi-thousand dollar job. I hooked up my scanner and pulled a P0752 (Shift Solenoid A Stuck On) and the generic P0700 (Transmission Control System Malfunction). While a solenoid could be bad, experience told me to check the source. We tested the solenoid circuits at the TCM connector and found the driver inside the module was shorted. Instead of a massive mechanical job, the fix was this exact VIN-programmed 2005-2006 SSR Transmission Module. An hour later, the customer was driving away with a perfectly shifting truck, having saved thousands.
Is Your SSR’s Transmission Acting Up?
A failing TCM can manifest in several ways. If you notice any of the following, it’s time to inspect your module. Ignoring these signs can lead to further transmission damage.
- ✔ Harsh, delayed, or unpredictable gear shifts.
- ✔ The vehicle is stuck in a single gear (limp mode).
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750-P0758, or other solenoid-related codes.
- ✔ A noticeable decrease in fuel economy.
- ✔ Complete loss of communication with the transmission.
A Straightforward Guide to Installation
For the 2005-2006 SSR Transmission Module, the replacement is a job most DIYers can handle in their own garage. On the SSR, the module is located on the front left-hand side of the frame. No specialized tools are required.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s computer systems.
- Locate the Module: Find the TCM mounted to the front LH frame of your SSR. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully unplug the wiring harnesses. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Securely reconnect the wiring harnesses, ensuring they click into place.
- Final Steps: Reconnect the battery terminal. Start the vehicle and let it idle for a few minutes. Use a standard OBD2 scan tool to clear any stored fault codes. Take the vehicle for a test drive to confirm smooth shifting.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the biggest benefit we offer. We program the module to your vehicle’s VIN before shipping. It arrives ready for plug-and-play installation, saving you the time, hassle, and expense of a dealership visit.
What is a core charge? Do I need to send my old part back?
There is no core charge for this part. You can keep your old module or dispose of it yourself, making the process simpler and faster for you.
Will this fix a P0700 check engine light code?
A P0700 code is a generic request from the TCM to the Engine Control Module (ECM) to turn on the check engine light. A faulty TCM is a very common cause of this code. Replacing the module will often resolve the P0700 and any other transmission-specific codes stored with it.
Is this a genuine GM part?
This is an OEM-quality module built to the same standards and specifications as the original factory part. It is designed for reliable, long-term performance and is backed by our one-year warranty.
