Restore Peak Performance to Your Chevrolet SSR
If you’re experiencing frustrating and unpredictable transmission behavior in your 2005-2006 Chevrolet SSR, a failing Transmission Control Module (TCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen how a faulty TCM can turn a great drive into a constant worry. This T42 Transmission Control Module, corresponding to part number 24252114, is the definitive solution to restore the crisp, reliable shifting your unique vehicle was designed to deliver. It’s not just a replacement part; it’s a permanent fix that arrives pre-programmed to your SSR’s specific VIN, eliminating the need for expensive dealership visits and complex programming procedures.
A Technician’s Notebook: The Ghost of P0751
I remember a 2006 Trailblazer—which shares a similar T42 module with the SSR—that came into my bay with a persistent P0751 (Shift Solenoid ‘A’ Performance/Stuck Off) code. The owner had already replaced the solenoid pack inside the transmission, but the harsh 1-2 shift and intermittent ‘limp mode’ continued. He was at his wit’s end. After verifying the wiring was intact, my diagnostics pointed directly to the TCM. The internal drivers that command the solenoids had weakened over time, a common failure point. We installed a VIN-programmed T42 module, cleared the codes, and the truck shifted like it just rolled off the assembly line. This isn’t just about replacing a part; it’s about correctly diagnosing the electronic brain behind the mechanical action.
Is Your SSR Exhibiting These Transmission Issues?
- âś” Sudden, harsh, or jarring gear shifts.
- âś” The vehicle feels stuck in one gear (often 2nd or 3rd) and won’t shift up or down.
- âś” Check Engine Light or Transmission Warning Light is illuminated with codes like P0700, P0750, P0751, or other solenoid-related faults.
- âś” Delayed engagement when shifting from Park to Drive or Reverse.
- âś” A noticeable drop in fuel economy or a transmission that seems to be overheating.
- âś” Complete loss of communication with the transmission module, preventing diagnostics.
Straightforward Installation Guide for Your Chevy SSR
Getting your SSR back in top form is a simple, straightforward process that you can complete in your own garage. The TCM is located on the front left-hand side of the frame. No special tools are required.
- Step 1: 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. - Step 2: Locate the Old Module
On the 2005-2006 SSR, the TCM is mounted to the front LH frame rail. Identify the module and its electrical connectors. - Step 3: Disconnect and Remove
Carefully unclip the wiring harness connectors. Then, unbolt the module from its mounting bracket. - Step 4: Install the New Module
Mount your new, VIN-programmed TCM onto the bracket and securely reconnect the wiring harnesses. You’ll hear a ‘click’ when they are properly seated. - Step 5: Finalize the Process
Reconnect the negative battery terminal. While our programming handles the critical setup, it’s always good practice to use a basic OBD2 scan tool to clear any stored fault codes from the ECU. Start the vehicle and enjoy a smooth ride!

Frequently Asked Questions
Why is VIN programming so important?
VIN programming loads your vehicle’s exact software, including shift points, torque converter strategy, and communication protocols. A generic module from a parts store or salvage yard won’t have this, leading to shifting problems, warning lights, or it may not work at all. Our service saves you a trip to the dealer for this mandatory step.
Is this a difficult part to install for a DIYer?
Not at all. For the SSR, it’s one of the more accessible modules. Located on the frame rail, it typically requires only basic hand tools and can be swapped in under 30 minutes, making it a perfect job for a weekend mechanic.
Will this module fix a P0700 code?
A P0700 is a generic code indicating the TCM has detected a fault. Often, the root cause is the TCM itself failing. While this module will resolve the issue if the TCM is the source, you should scan for more specific codes (like P07xx) to confirm the diagnosis.
Do I need to return my old module (core)?
No. We do not require a core return. You can keep your old part, which simplifies the process and gets your vehicle repaired faster without worrying about core charges or return shipping.
What kind of warranty is included?
This module is backed by our one-year, hassle-free warranty, giving you peace of mind and confidence in your repair.
