Restore Peak Performance to Your Chevrolet SSR
If your 2005-2006 Chevrolet SSR is suffering from erratic shifting, getting stuck in gear, or throwing transmission codes, the problem is likely a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen how a faulty TCM can sideline an otherwise perfect vehicle. This isn’t just an inconvenience; it affects drivability, fuel economy, and safety. This replacement T42 TCM, part number 24235340, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
A Technician’s Notebook: The Misleading Solenoid Code
A customer brought in a 2008 GMC Envoy with the classic 4L60E complaint: harsh 1-2 shift and a P0751 (Shift Solenoid ‘A’ Stuck Off) code. The previous shop had already replaced the solenoid, but the problem returned within a week. My diagnostic process led me straight to the T42 TCM. The internal drivers for the solenoids had become weak, causing intermittent commands that mimicked a solenoid failure. After installing one of our VIN-programmed modules, the shifting was immediately crisp and the code never came back. This highlights why replacing the TCM is often the correct fix, saving you from chasing phantom component failures and wasting money on unnecessary internal transmission work.
Is Your SSR’s Transmission Showing These Telltale Signs?
A failing TCM sends clear warning signals. If you’re experiencing any of the following, it’s time to consider a replacement 2005-2006 SSR Transmission Control Module. Ignoring these symptoms can lead to more severe transmission damage.
- ✔ Unpredictable or harsh gear changes that slam into place.
- ✔ The vehicle enters ‘limp mode,’ refusing to shift out of a single gear (often 2nd or 3rd).
- ✔ Your Check Engine Light is on with Diagnostic Trouble Codes (DTCs) like P0700, P0750, P0753, or other solenoid-related faults.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ A noticeable drop in fuel efficiency and potential for transmission overheating.
- ✔ Complete loss of communication with the transmission module.
Your Straightforward Installation Guide
Getting your SSR back on the road is easier than you think. This module is designed for a simple, direct-fit replacement that a DIY enthusiast can complete in their own garage in under 30 minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic component replacement.
- Locate the Module: On the 2005-2006 SSR, the TCM is conveniently located on the front left-hand (driver’s side) frame rail.
- Unplug and Unbolt: Carefully disconnect the electrical harness connectors. Be gentle with the locking tabs. Then, remove the mounting bolts holding the old module in place.
- Install the New TCM: Mount your new, VIN-programmed module in the same location and secure it with the bolts. Reconnect the electrical harnesses, ensuring they click securely into place.
- Final Steps: Reconnect the battery terminal. While our programming handles the critical setup, it’s good practice to use a basic scan tool to clear any stored fault codes from the vehicle’s memory.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and the latest GM software onto the module before shipping. This ensures it communicates perfectly with your SSR’s engine computer and other systems right out of the box, eliminating the need for expensive dealership programming.
Will this fix my specific transmission problem?
This module is the direct solution for failures within the TCM itself, which cause the symptoms listed above. If you’ve been diagnosed with a bad transmission computer or have matching DTCs, this part is designed to resolve those issues.
Do I need any special tools for installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts, are all you need. The most important part of the job is ensuring the battery is disconnected.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and return shipping costs.
