Restore Peak Performance to Your Chevrolet SSR
Is your 2005-2006 Chevrolet SSR suffering from erratic shifting, getting stuck in gear, or throwing transmission codes? These are classic signs of a failing Transmission Control Module (TCM). As the electronic brain of your automatic transmission, the TCM is responsible for every gear change. When it fails, it can make your unique retro-truck feel unreliable and frustrating to drive. This T42 TCM, part number 24239926, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
A Technician’s Notebook
I remember a 2005 SSR rolling into my bay with a complaint that was driving the owner crazy. It would shift perfectly for days, then suddenly start banging into gear or refuse to shift out of 2nd. The check engine light was on with a P0700 code, which is a generic request from the TCM to illuminate the light. After scanning the TCM itself, I found codes for intermittent solenoid circuit faults. Instead of chasing phantom wiring issues or condemning a perfectly good transmission, we went straight for the common culprit: the T42 module. After a quick swap with a VIN-programmed unit, all the codes were gone, and the SSR was shifting like it just left the factory. This simple replacement saved the customer from a potential multi-thousand-dollar transmission rebuild.
Is Your SSR Exhibiting These Transmission Problems?
A faulty TCM can manifest in several ways. If you’re experiencing any of the following, it’s highly likely your module is the root cause. A failing 2005-2006 SSR TCM can cripple your vehicle’s performance and reliability.
- ✔ Harsh, delayed, or unpredictable gear shifts.
- ✔ Vehicle is stuck in “limp mode” (usually second or third gear).
- ✔ Check Engine Light is on with transmission-related Diagnostic Trouble Codes (DTCs) like P0700, P0750, P0753, P0758, etc.
- ✔ Complete loss of upshifting or downshifting capabilities.
- ✔ Poor fuel economy due to inefficient shifting and torque converter operation.
- ✔ Intermittent loss of communication with the TCM, causing erratic behavior.
DIY-Friendly Installation for Your Chevy SSR
One of the best features of this module is its simple installation. Because we program it to your VIN before shipping, you don’t need a trip to the dealer. For the Chevy SSR, the process is especially straightforward.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: On the 2005-2006 SSR, the TCM is conveniently located on the front left-hand (driver’s side) frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Mount your new, pre-programmed module in the same location and securely reconnect the electrical harnesses.
- Reconnect and Verify: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. If you have a basic OBD2 scan tool, use it to clear any stored fault codes. Take a test drive to confirm the shifting issues are resolved.
