Restore Peak Performance to Your Chevrolet SSR
Is your 2005-2006 Chevrolet SSR suffering from frustrating transmission problems? A faulty Transmission Control Module (TCM) can ruin the driving experience of this unique performance truck, causing everything from jarring shifts to leaving you stranded in limp mode. This replacement T42 TCM, part number 24235754, is the definitive solution. It arrives pre-programmed to your SSR’s specific VIN, making it a true plug-and-play fix that restores the smooth, responsive shifting you expect. No dealership visits, no expensive programming tools—just a straightforward repair that gets you back on the road with confidence.
Is Your SSR Showing These Symptoms?
A failing TCM often displays clear warning signs. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement. Over my 20+ years in diagnostics, these are the most common complaints I’ve seen tied directly to a bad 2005-2006 SSR TCM.
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- ✔ The vehicle is stuck in a single gear (often 2nd or 3rd), a condition known as “limp mode.”
- ✔ Check Engine Light or Transmission Warning Light is on with Diagnostic Trouble Codes (DTCs) like P0700, P0751, P0756, or other solenoid-related faults.
- ✔ A complete failure to upshift or downshift, leading to poor acceleration and terrible fuel economy.
- ✔ Intermittent loss of communication with the module, causing unpredictable performance.
Case Study: A Tricky Diagnosis
A customer brought in their ’05 SSR with a complaint that stumped a couple of other shops: the transmission would occasionally slip or shift hard, but only after driving for 30-40 minutes on a hot day. There were no consistent codes, just a general P0700 (Transmission Control System Malfunction) stored in history. We suspected the TCM was failing due to heat soak. After letting the truck run in the bay to replicate the condition, the symptoms appeared. We swapped in a VIN-programmed TCM, and the problem vanished instantly. The original module’s internal circuits were breaking down under heat, a classic failure mode for these electronics.
Your Straightforward Installation Guide
One of the best features of this module is its ease of installation. For the Chevy SSR, the process is particularly simple and requires only basic hand tools, getting your truck back to normal in under an hour.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s adaptive memory.
- Locate the Module: On the 2005-2006 SSR, the TCM is located on the front left-hand (driver’s side) frame rail. It’s an externally mounted black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical harnesses from the old TCM. Press the release tabs firmly to avoid damaging the clips. Then, unbolt the module from its mounting bracket on the frame.
- Install the New TCM: Mount your new, pre-programmed TCM onto the bracket and securely tighten the bolts. Reconnect the electrical harnesses, ensuring they click firmly into place.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and let it idle for a few minutes. If you have a basic scan tool, it’s good practice to clear any lingering fault codes from the system. Take the vehicle for a test drive to confirm smooth shifting.

Frequently Asked Questions
Does this 2005-2006 SSR TCM require any additional programming?
No. We program the module to your vehicle’s VIN before shipping. It is ready for installation right out of the box, with no need for a trip to the dealer or a special scan tool.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module or dispose of it without the hassle of returning it.
What kind of warranty is included?
This transmission control module is backed by our comprehensive one-year warranty, covering any defects or functional issues for your peace of mind.
Will this fix a P0700 trouble code?
A P0700 code is a general fault request from the TCM to the Engine Control Module (ECM) to turn on the Check Engine Light. While a faulty TCM is a very common cause, this code indicates a problem exists within the transmission’s control system. Replacing a failed TCM will resolve the underlying issue that triggers the P0700.
What information do you need to program the module?
We only need your vehicle’s 17-digit Vehicle Identification Number (VIN). You can typically find this on your driver’s side door jamb sticker, your insurance card, or at the base of the windshield on the driver’s side.
