If your 2005-2006 Chevrolet SSR is suffering from erratic shifting, getting stuck in gear, or throwing transmission codes, the culprit is often a failing Transmission Control Module (TCM). As an automotive diagnostician with over two decades of experience, I’ve seen countless GM vehicles, including the unique SSR, sidelined by these issues. This T42 TCM, part number 24239224, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair that restores the crisp, reliable performance you expect.
The TCM is the brain of your automatic transmission, controlling everything from shift points to torque converter clutch engagement. When it fails, communication breaks down, leading to the frustrating and potentially damaging symptoms you’re experiencing. Our process eliminates the guesswork and costly dealership visits. We flash the module with the latest GM software updates using your VIN, ensuring it works seamlessly with your SSR’s powertrain control module (PCM) right out of the box.
Case Study: The Ghost in the SSR’s Transmission
A customer brought in a beautiful 2006 SSR with an intermittent but severe problem: it would occasionally refuse to shift out of 2nd gear after coming to a stop. No warning lights were consistently on, but a scan revealed a stored P0700 (Transmission Control System Malfunction) code. We checked fluid levels and solenoid resistances, which were all perfect. After monitoring live data, we saw the TCM command for the 2-3 shift was dropping out randomly. This pointed directly to an internal failure in the original module. We installed one of our VIN-programmed T42 TCMs, and the problem was solved instantly. The customer saved hundreds compared to the dealership and was back to enjoying his retro roadster the same day.
Solving Problems with the 2005-2006 SSR TCM
A faulty TCM doesn’t just affect performance; it impacts safety and fuel economy. By replacing your failing unit with this quality-tested module, you’re not just fixing a part—you’re restoring the integrity of your vehicle’s entire drivetrain. This module is a direct replacement for a wide range of GM vehicles, ensuring broad compatibility and proven reliability. It directly interchanges with part numbers like 24252114, 24234503, and 24239224, making it the right choice for your repair.
Is Your SSR’s Transmission Acting Up? Check for These Signs
- ✔ Harsh, delayed, or unpredictable gear shifts.
- ✔ Vehicle is stuck in “limp mode,” often in a single gear (like 2nd or 3rd).
- ✔ The Check Engine Light or a transmission-specific warning light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ The transmission feels like it’s slipping between gears or fails to engage properly.
Your Step-by-Step Guide to a Smooth Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and reset the system.
- ✔ Locate the Module: On the Chevrolet SSR, the TCM is typically found on the front left-hand (driver’s side) frame rail.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old TCM. Then, unbolt the module from its mounting bracket.
- ✔ Install the New TCM: Mount the new, pre-programmed module in the same location and securely reconnect the electrical harnesses.
- ✔ Final Steps: Reconnect the battery terminal. While our programming handles the critical setup, it’s good practice to use a basic OBD2 scan tool to clear any lingering fault codes from the system’s memory.

What does ‘VIN Programmed’ mean for me?
What does ‘VIN Programmed’ mean for me?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software onto the module before shipping. This ensures it communicates perfectly with your vehicle’s other computers, requiring no extra programming or trips to the dealer. It’s ready for installation right out of the box.
Do I need to send my old TCM back?
No, there is no core charge for this part. You can keep your old module or dispose of it, making the process faster and more convenient for you.
Is this a difficult part for a DIYer to install?
For most individuals with basic hand tools, this is a very straightforward repair. The module is typically easy to access in the engine bay, and the process involves unplugging connectors and removing a few bolts. The entire job can usually be completed in under 30 minutes.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a failing TCM is a very common cause, this code can also be triggered by other transmission issues. However, if you’re also experiencing symptoms like erratic shifting or limp mode, replacing the TCM is the most likely solution.
