Is Your 2005-2006 Chevrolet SSR Shifting Erratically?
If you’re experiencing harsh shifts, delayed gear engagement, or your Chevrolet SSR is stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it fails, it can mimic serious mechanical transmission problems, leading to frustrating and often incorrect diagnoses. This VIN-programmed T42 TCM is the definitive solution to restore the smooth, responsive performance your unique vehicle was built for.
From the Diagnostic Bay
We recently had a 2006 SSR in the shop with classic symptoms of a failing transmission. The owner was convinced he needed a complete transmission rebuild, quoting thousands of dollars from another shop. After plugging in our scan tool, we saw a flurry of solenoid circuit codes and a P0700 (Transmission Control System Malfunction). Instead of pulling the transmission, we started with the brain. We swapped in a VIN-programmed T42 TCM, cleared the codes, and took it for a test drive. The shifts were instantly crisp and smooth, just like it had left the factory. The owner saved a fortune by correctly identifying the electronic failure first. This is a common story for the reliable 4L60E/4L65E transmissions these vehicles use; the electronics are often the first point of failure.
Symptoms of a Failing 2005-2006 SSR TCM
Your vehicle’s computer system is designed to alert you to problems. If your TCM is failing, you’ll likely notice one or more of the following issues:
- ✔ Harsh Shifting and Gear Slipping: Abrupt, jerky shifts or a feeling that the transmission is slipping between gears.
- ✔ Warning Lights: The Check Engine Light or a dedicated transmission warning light will illuminate on your dashboard.
- ✔ Limp Mode Activation: The vehicle may refuse to shift out of a single gear (usually 2nd or 3rd) to prevent further damage.
- ✔ Diagnostic Trouble Codes (DTCs): A scan tool will reveal codes like P0700, P0750, or other transmission solenoid-related faults.
- ✔ Delayed Engagement: A noticeable pause after shifting from Park into Drive or Reverse before the transmission engages.
- ✔ Poor Fuel Economy: Inefficient shifting and torque converter lock-up can lead to a sudden drop in your MPG.
The Plug-and-Play Solution: VIN Programming Included
The biggest hurdle in replacing modern electronic modules is the need for expensive dealership programming. We eliminate that step entirely. When you order from us, we pre-program this T42 TCM with your vehicle’s specific Vehicle Identification Number (VIN). This process ensures the module has the latest GM software and is perfectly calibrated for your SSR’s specific configuration. The result is a true plug-and-play installation—no extra tools, no trip to the dealer, and no hidden fees. It arrives ready to install right out of the box.
This module is a direct replacement for a wide range of original equipment part numbers, including 24252114, 24234503, 24230461, 24234274, 24235340, and many more, guaranteeing compatibility and OEM-level function.
Simple Installation to Get You Back on the Road
For the 2005-2006 Chevrolet SSR, the TCM is conveniently located on the front left-hand frame rail, making it accessible for the home mechanic. The entire replacement process can typically be completed in under 30 minutes with basic hand tools.
- Safety First: Disconnect the negative terminal on your vehicle’s battery.
- Locate the Module: Find the TCM on the front LH frame of your SSR.
- Disconnect and Remove: Carefully unplug the electrical connectors and unbolt the old module from its mounting bracket.
- Install the New TCM: Mount your new, VIN-programmed module in place, securely reconnect the electrical harnesses, and then reconnect the vehicle’s battery.
- Final Steps: Start the vehicle. While our programming resolves most issues, it’s good practice to use a basic OBD2 scan tool to clear any stored historical fault codes from the system.
With no core charge, you don’t have to worry about the hassle and expense of sending your old, faulty part back. It’s a straightforward fix that restores the integrity of your vehicle’s powertrain.
Frequently Asked Questions
What is VIN programming and why do I need it?
VIN programming installs your vehicle’s specific software onto the new TCM. This ensures the module communicates correctly with your engine computer, ABS, and other systems. Without it, the vehicle will not shift correctly or may not even start. We handle this for you so it’s ready for immediate installation.
Is this a genuine GM part?
This is an OEM-quality component built to the exact specifications of the original General Motors part. It is designed to meet or exceed original performance and reliability standards and is backed by our one-year warranty.
Will this fix my P0700 diagnostic trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. This is often accompanied by more specific codes. Replacing a faulty TCM is the most common fix for a P0700 and its related codes. Our module, programmed with the latest software, is designed to resolve these electronic faults.
Do I need to perform a transmission relearn procedure after installation?
In most cases, a specific relearn procedure is not required. The pre-programming to your VIN handles the critical setup. The vehicle’s systems will naturally adapt to the new module within the first few drive cycles. Simply install it and drive.
What if I have a different GM vehicle?
While this part is listed for the SSR, the T42 TCM was used in dozens of GM vehicles from 2006-2014, including the Silverado, Tahoe, Impala, and GMC Sierra. Please verify the part number or use our vehicle fitment tool to ensure compatibility with your specific model.
