If the transmission in your 2005-2006 Chevrolet SSR is acting up, you’re not just losing performance—you’re losing the joy of driving your unique retro-truck. As a tech with over two decades of experience, I’ve seen countless GM vehicles sidelined by a faulty Transmission Control Module (TCM). The symptoms are unmistakable: harsh, unpredictable shifts, getting stuck in gear, or a persistent check engine light that just won’t go away. This isn’t just an annoyance; it’s a critical failure that can lead to more severe transmission damage if ignored.
This T42 TCM, part number 24252114, is the definitive solution. We take the guesswork and dealership hassle out of the equation. Before we ship it, we program the module to your SSR’s specific Vehicle Identification Number (VIN). This means it arrives at your door ready for a true plug-and-play installation. It will communicate flawlessly with your vehicle’s Powertrain Control Module (PCM) and other systems, restoring the crisp, decisive shifting you expect. Don’t let a bad module keep your SSR parked. Get the reliable, pre-programmed fix and get back to turning heads on the road.
Case Study: The Limp-Mode SSR
A customer brought in a 2006 SSR with a classic complaint: it was stuck in what felt like third gear. The check engine light was on, and his scanner pulled a P0700 (Transmission Control System Malfunction) and a handful of solenoid-specific codes. He was worried he needed a full transmission rebuild. After checking the fluid and connectors, my experience pointed straight to the TCM. These modules, located on the front left frame on the SSR, are exposed to heat and vibration, which can cause internal circuit failure over time. We swapped in one of our VIN-programmed T42 modules. After a 20-minute install and clearing the codes, the SSR was shifting perfectly through all gears. It’s a prime example of how the right part saves you from a thousand-dollar-plus repair bill.
Is Your SSR Exhibiting These Transmission Problems?
A failing TCM can manifest in several ways. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement. In my shop, over 80% of these symptoms on GM vehicles of this era trace back to the TCM.
- ✔ Harsh, banging, or erratic gear shifts.
- ✔ The vehicle is stuck in “limp mode” (usually second or third gear).
- ✔ Check Engine Light is illuminated with transmission-related Diagnostic Trouble Codes (DTCs) like P0700, P0750, P0753, P0758.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Failure to upshift or downshift properly.
- ✔ Poor fuel economy and a feeling of sluggish performance.
- ✔ Complete loss of communication with the transmission.
Straightforward Installation for Your Chevy SSR
You don’t need to be a master mechanic to install this part. With basic hand tools, you can have your SSR back in top form in under an hour. The module is typically found on the front left-hand side of the frame.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the TCM: On the 2005-2006 SSR, the TCM is mounted to the front left (driver’s side) frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Securely reconnect the electrical harnesses, ensuring they click into place.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and use a standard OBD2 scan tool to clear any lingering fault codes from the computer’s memory.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean for me?
It means this module is not a generic, off-the-shelf part. We load it with the specific software and calibrations for your SSR’s exact configuration (engine, axle ratio, tire size) using your VIN. This ensures perfect communication and performance the moment you install it, saving you a trip to the dealership and their programming fees.
Do I need to send my old TCM back (core charge)?
No. There is no core charge for this part. You can keep your old module or dispose of it responsibly without any extra hassle or cost.
Will this part fix a P0700 code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause (like an internal TCM failure that triggers the code), you should always ensure other components like wiring and solenoids are in good condition. However, a faulty TCM is the most common culprit.
Is any other relearn procedure required after installation?
No. Because the unit is pre-programmed to your VIN, no complex relearn procedures are necessary. After installation and clearing any old codes with a scan tool, the system is ready to go. The module will adapt to your driving style over the first few drive cycles.
