Tired of Transmission Troubles in Your Chevy SSR?
If your 2005-2006 Chevrolet SSR is suffering from harsh shifts, getting stuck in gear, or throwing transmission codes, the culprit is often a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen firsthand how a faulty T42 module can sideline these unique sport trucks. A failing TCM doesn’t just affect performance; it impacts drivability and your confidence on the road. This isn’t a problem you can ignore, as it can lead to more significant transmission damage over time.
This is a direct-replacement, OEM-quality T42 TCM, part number 24235732, that arrives pre-programmed to your SSR’s specific Vehicle Identification Number (VIN). This critical step ensures it communicates flawlessly with your vehicle’s engine computer and other systems right out of the box, eliminating the need for an expensive trip to the dealership for programming. It’s the definitive solution to restore the crisp, predictable shifting your vehicle had from the factory.
From the Diagnostic Bay: The Hidden Culprit
A customer brought in a 2006 Chevy SSR with what they described as ‘possessed’ transmission behavior. It would randomly refuse to shift out of 2nd gear, and the check engine light was on with a generic P0700 code. They had already replaced two shift solenoids based on a previous shop’s advice, but the problem persisted. After a quick data stream analysis, I noticed the TCM was intermittently losing communication. These T42 modules, especially on vehicles like the SSR, are located in the engine bay where they endure constant heat cycles. Over the years, this leads to internal circuit board failure. We installed a VIN-programmed 2005-2006 SSR TCM, cleared the codes, and the truck was shifting perfectly within an hour. It saved the customer from a costly, unnecessary transmission rebuild.
Common Signs of a Failing T42 TCM
If you’re experiencing any of the following, a faulty TCM is a likely cause. Don’t let these symptoms go unchecked:
- ✔ Vehicle is stuck in ‘limp mode’ (usually second or third gear).
- ✔ Harsh, banging shifts or delayed gear engagement.
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, P0753, or other solenoid-related faults.
- ✔ The transmission refuses to upshift or downshift properly.
- ✔ A noticeable drop in fuel economy.
- ✔ Complete loss of communication with the scan tool.
A Straightforward Guide to Installation
For the handy DIYer or professional mechanic, installing this 2005-2006 SSR TCM is a simple process that typically takes less than 30 minutes. 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 Chevrolet SSR, the TCM is typically located 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 Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock.
- 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 clear any stored fault codes from the vehicle’s memory. Start the vehicle and test drive to confirm smooth shifting.
