Restore Peak Performance to Your 2005-2006 Chevrolet SSR
Is your 2005-2006 Chevrolet SSR suffering from erratic shifting, getting stuck in gear, or throwing transmission-related trouble codes? Before you start pricing out a costly transmission rebuild, the culprit is often a faulty Transmission Control Module (TCM). As the electronic brain of your automatic transmission, a failing TCM can cause a host of frustrating and potentially damaging issues. I’ve seen it countless times in my 20+ years of diagnostics: a perfectly good transmission sidelined by a bad module. This VIN-programmed T42 TCM, part number 24230461, is the direct-fit, reliable solution to get your unique SSR back to shifting smoothly and predictably.
This isn’t just a replacement part; it’s a complete solution. We handle the programming for you. By providing your vehicle’s VIN at checkout, we flash the module with the latest GM software specific to your SSR. This means no expensive trips to the dealership for programming—it arrives ready for a true plug-and-play installation. This step is critical for ensuring the transmission communicates correctly with the engine and other vehicle systems, restoring the original shift patterns and fuel efficiency you expect. A properly functioning 2005-2006 SSR TCM is essential for the health and longevity of your entire drivetrain.
Case Study: A Tricky Diagnosis
A customer brought in his ’06 SSR with classic symptoms: it would randomly refuse to shift out of 2nd gear and the check engine light was on. He was worried he needed a new 4L60E transmission. I connected my scan tool and pulled a P0751 (Shift Solenoid ‘A’ Performance/Stuck Off). While this can point to a bad solenoid, my experience with these platforms told me to check the TCM first. After a quick inspection of the wiring, I swapped in a programmed TCM. The issue vanished instantly. The original module had an internal fault causing it to misinterpret sensor data. A 30-minute fix saved him over two thousand dollars. That’s why I always recommend starting with the brain before condemning the body.
Common Signs of a Failing GM TCM
- ✔ Vehicle is stuck in “limp mode” (usually second or third gear) to protect the transmission.
- ✔ Harsh, delayed, or unpredictable gear shifts that bang into place.
- ✔ The check engine light or transmission warning light is illuminated on your dash.
- ✔ You’ve pulled Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-specific codes.
- ✔ A noticeable drop in fuel economy due to inefficient shifting and torque converter operation.
- ✔ The transmission seems to slip between gears or fails to engage from Park to Drive or Reverse.
- ✔ Complete loss of communication with the module, leading to a no-shift condition.
A Straightforward Guide to Installation
Replacing the 2005-2006 SSR TCM is a job most DIY enthusiasts can handle in their own garage in under 30 minutes. No specialized tools are required.
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting any electronic component replacement.
- Locate the Module: On the 2005-2006 SSR, the TCM is typically mounted on the front left-hand (driver’s side) frame rail.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Mount your new, pre-programmed module in the same location and securely fasten it. Reconnect the wiring harnesses, ensuring they click into place.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s good practice to use a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory.

Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the ECM to turn on the check engine light. While this module can resolve the underlying issue causing the P0700, you should scan for more specific P-codes (like P07xx) to confirm the diagnosis. A faulty TCM is a very common cause.
