If you’re dealing with the frustration of a Chevrolet SSR that’s shifting erratically, getting stuck in gear, or throwing transmission codes, you’ve come to the right place. As a technician with over two decades of experience under the hood, I understand that a faulty Transmission Control Module (TCM) can turn your unique, fun-to-drive truck into a source of constant worry. This isn’t just a component; it’s the brain of your automatic transmission. This OEM-quality T42 TCM is the definitive solution, arriving fully programmed to your SSR’s specific VIN for a true plug-and-play repair.
This module eliminates the need for expensive dealership visits for programming. It’s designed to directly address the root cause of many common 4L60E transmission issues, restoring the crisp, predictable shifting performance you expect. By precisely managing shift points, torque converter lockup, and line pressure, this 2005-2006 SSR TCM ensures your vehicle operates reliably and efficiently, whether you’re on a weekend cruise or your daily commute.
Case Study: The Ghost in the SSR’s Transmission
A few months back, a 2006 SSR was brought into my bay with a classic ‘ghost’ problem. The owner complained of intermittent, hard 1-2 shifts and occasionally getting stuck in 3rd gear (limp mode), but only after the truck was fully warmed up. No single solenoid code was present, just a generic P0700 (Transmission Control System Malfunction). We checked fluid levels, wiring, and solenoids—all were fine. After seeing this pattern dozens of times on GM vehicles of this era, I knew the culprit was likely the TCM failing under heat. We installed a VIN-programmed T42 module, and the problem vanished instantly. It’s a textbook example of how a failing module can mimic mechanical issues, making an accurate diagnosis key.
Is Your SSR Exhibiting These Telltale Signs?
A failing TCM often broadcasts its issues through clear symptoms. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Harsh, slamming, or delayed gear shifts.
- ✔ The vehicle is stuck in ‘limp mode’ and won’t shift out of 2nd or 3rd gear.
- ✔ Your Check Engine Light or Transmission Warning Light is on.
- ✔ You’ve pulled Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- ✔ Unexplained drops in fuel economy or a transmission that seems to be overheating.
- ✔ Complete loss of communication with the transmission, resulting in a no-shift condition.
Your 30-Minute Path to a Smooth Ride
One of the best features of this module is its straightforward installation. For the 2005-2006 SSR, the process is simple enough for a confident DIYer to complete in their own garage. No specialized tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: On the SSR, the TCM is conveniently located on the front left-hand (driver’s side) frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note the tab locations to avoid damage. Then, unbolt the old module from its mounting bracket.
- Install the New TCM: Mount your new, pre-programmed module in the same location and securely fasten it. Reconnect the electrical harnesses until they click into place.
- Final Steps: Reconnect the battery terminal. While our programming resolves most issues, it’s good practice to use a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory.

Frequently Asked Questions
What does ‘VIN Programmed’ actually 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 SSR’s engine computer and other systems right out of the box, just like an original part from the factory.
Do I need to take my truck to a dealer after installation?
No. The pre-programming process completely eliminates the need for a trip to the dealership for expensive flashing or setup. This is a true plug-and-play solution.
Is this part difficult to install for a DIY mechanic?
Not at all. For the 2005-2006 SSR, the TCM is located in an accessible spot on the frame rail. With basic hand tools and about 30 minutes, most people can perform the swap themselves.
Will this fix a P0700 code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying cause (like internal failure), you should ensure there are no wiring or sensor issues first. In many cases, a faulty TCM is the root cause.
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 sending it back, saving you time and money.
