Restore Peak Performance to Your Chevrolet SSR
Is your 2005-2006 Chevrolet SSR suffering from erratic shifting, getting stuck in gear, or throwing transmission-related check engine lights? 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 and torque converter operation. When it falters, drivability and reliability suffer. This T42 TCM, part number 24255280, is the definitive solution, arriving pre-programmed to your SSR’s specific VIN for a true plug-and-play fix.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2006 SSR rolling into my bay with a complaint that stumped a few other shops. The owner described intermittent, violent 1-2 shifts and occasional failure to upshift, but it would never act up on a test drive. There were no hard codes, just a generic P0700 (Transmission Control System Malfunction) stored. After checking the fluid, solenoids, and wiring harness, everything looked perfect. On a hunch, I monitored the TCM data stream and noticed erratic signal outputs just before a harsh shift. The internal processors were failing under load. We replaced it with a VIN-programmed T42 module like this one, and the SSR shifted like it just left the factory. It’s a reminder that sometimes the problem is the computer itself, not the mechanical parts it controls.
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 culprit. Over my 20+ years, these are the most common symptoms I’ve seen tied directly to a failing 2005-2006 SSR TCM.
- âś” Harsh, slamming shifts or delayed gear engagement.
- âś” Vehicle is stuck in “limp mode,” often refusing to shift out of 2nd or 3rd gear.
- âś” The Check Engine Light or Transmission Warning Light is illuminated with Diagnostic Trouble Codes (DTCs) such as P0700, P0750, P0753, P0758, or other solenoid-related faults.
- âś” Inconsistent upshifting or downshifting, leading to poor acceleration and terrible fuel economy.
- âś” Complete loss of communication with the TCM, resulting in a no-shift condition.
DIY-Friendly Installation for Your Chevy SSR
One of the best features of this module is that it eliminates the need for a costly trip to the dealership for programming. We handle that for you. Installation is a straightforward process that most DIY enthusiasts can complete in their own garage in under 30 minutes with basic hand tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning 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 unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle over time. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Mount the new module securely onto the bracket and firmly reconnect the electrical harnesses until they click into place.
- Final Steps: Reconnect the battery terminal. While the module is pre-programmed, it’s always good practice to use a basic scan tool to clear any lingering fault codes from the vehicle’s memory. Start the vehicle and enjoy smooth, responsive shifting!
