Restore Peak Performance to Your Chevrolet SSR
Is your 2005-2006 Chevy SSR suffering from delayed, harsh, or unpredictable shifting? Are you stuck in limp mode or staring at a persistent check engine light? Don’t let a faulty Transmission Control Module (TCM) sideline your unique sport truck. As a technician with over two decades of experience, I’ve seen firsthand how a failing TCM can turn a thrilling drive into a frustrating ordeal. This OEM-quality T42 TCM, part number 24256960, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a true plug-and-play fix.
The TCM is the brain of your automatic transmission, orchestrating every gear change, managing torque converter lockup, and monitoring system health. When it fails, symptoms can range from minor annoyances to complete transmission shutdown. This replacement module is engineered to restore the precise, factory-spec performance your SSR’s 4L60E or 4L65E transmission was designed for, ensuring smooth operation and long-term reliability without a costly trip to the dealership for programming.
From the Diagnostic Bay: The Intermittent SSR Shifting Mystery
A customer brought in his ’05 SSR with a complaint that baffled him: the truck would shift perfectly when cold, but after 20-30 minutes of driving, it would start banging into gear and occasionally refuse to shift out of 2nd. He’d get a generic P0700 code, but nothing specific. In my shop, I’ve diagnosed hundreds of these T42 module failures. The root cause is often internal circuit board breakdown due to years of heat cycles. The module on the SSR is located on the front left frame rail, where it’s exposed to significant engine and road heat. This heat causes microscopic cracks in solder joints, leading to intermittent connections that only appear when the module gets hot. Swapping in a new, pre-programmed 2005-2006 SSR TCM solved his problem instantly, a classic case where the symptoms pointed directly to the electronic controller.
Is Your SSR Exhibiting These Telltale Signs?
- ✔ Harsh, erratic, or delayed gear shifts that disrupt your drive.
- ✔ The vehicle is stuck in a single gear (often called “limp mode”).
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700 (Transmission Control System Malfunction), P0750-P0758 (Shift Solenoid errors), or other transmission-related faults.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting.
- ✔ The transmission feels like it’s slipping between gears or failing to engage properly.
A Straightforward Installation for Your SSR
Getting your truck back in top form is a simple, straightforward process that most DIY enthusiasts can complete in their own garage. 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 system.
- Locate the Module: On the 2005-2006 SSR, the TCM is mounted 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 Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s always best practice to use a standard OBD2 scan tool to check for and clear any stored fault codes. Start the vehicle and enjoy your restored transmission performance!

Do I need to take my truck to the dealer for programming?
Do I need to take my truck to the dealer for programming?
No. This module comes fully pre-programmed to your vehicle’s VIN. It is a true plug-and-play solution, saving you the time and expense of a dealership visit.
What if I install it and still have shifting problems?
While the TCM is the most common point of failure for these symptoms, other issues like faulty solenoids or internal mechanical problems can cause similar behavior. We recommend a full diagnostic scan if problems persist. However, replacing a known-faulty TCM is the correct first step in the diagnostic process.
Is there a core charge for my old module?
No, there is no core charge. You can keep your old part without any hassle or need to return it.
Will this module fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. Often, a failing TCM sets this code itself. Replacing the module will typically resolve the P0700 code if the module was the source of the fault.
