Restore Your SSR’s Shifting Performance
If you’re dealing with the headaches of a faulty transmission in your 2005-2006 Chevrolet SSR, you know how frustrating it can be. One minute your truck is a joy to drive, the next it’s shifting harshly, getting stuck in gear, or throwing a check engine light. As a technician with over two decades of experience, I’ve seen countless drivers spend a fortune chasing down what they think is a mechanical transmission failure, when the real culprit is a failing Transmission Control Module (TCM). This VIN-programmed T42 TCM, part number 24243901, is the definitive solution to get your vehicle operating smoothly and reliably again.
A Technician’s Notebook
I remember a 2006 Trailblazer that came into the shop with a classic case of “limp mode.” The owner was convinced his 4L60E transmission was shot. It would barely shift out of second gear, and the dash was lit up. He’d already replaced two shift solenoids based on some forum advice. After a quick scan, I saw the familiar P0700 code—a general transmission fault request. Digging deeper, communication with the TCM was intermittent. Instead of starting a costly transmission teardown, we ordered a VIN-programmed TCM. Thirty minutes after it arrived, the module was in, codes were cleared, and the Trailblazer was shifting like it just rolled off the factory floor. It’s a powerful reminder: always check the electronics first. This part saves time, money, and unnecessary mechanical work.
Is Your SSR Exhibiting These Telltale Signs?
A failing TCM doesn’t always mean a complete transmission breakdown. Often, the symptoms are intermittent and confusing. Here are the most common indicators that your transmission module is the problem:
- ✔ Harsh, jerky, or erratic gear shifts.
- ✔ The vehicle is stuck in a single gear (often called “limp mode”).
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Check Engine Light or Transmission Warning Light is on with codes like P0700, P0750, or other solenoid-related faults.
- ✔ Failure to upshift or downshift properly, leading to poor acceleration.
- ✔ A noticeable decrease in fuel economy.

- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Old Module: Find the TCM on the front LH frame. It will have several electrical connectors attached.
- Disconnect and Remove: Carefully unplug the wiring harnesses. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Securely reconnect the wiring harnesses, ensuring they click into place.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We program the module to your vehicle’s VIN before shipping it. It arrives ready for a plug-and-play installation, saving you hundreds in dealership fees.
What is the difference between a TCM and a PCM?
The Powertrain Control Module (PCM) often controls both the engine and transmission. In many GM vehicles of this era, the Transmission Control Module (TCM) is a separate, dedicated computer that exclusively manages automatic transmission functions for improved performance and diagnostics.
Will this fix a P0700 trouble code?
A P0700 is a generic code indicating the TCM has detected a fault. While this module often resolves the root cause (like an internal TCM failure), you should always diagnose any other codes that are present. In many cases, a faulty TCM is the source of the problem.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your old module or dispose of it without any extra cost or hassle.
What tools do I need for installation?
For most vehicles, including the SSR, you will only need basic hand tools like a socket set to remove the mounting bolts and a flathead screwdriver to help with connector tabs. An OBD2 scanner is recommended to clear codes after installation.
