Restore Your SSR’s Transmission Performance
Is your 2005-2006 Chevrolet SSR suffering from frustrating and unpredictable shifting? A faulty Transmission Control Module (TCM) is often the culprit behind harsh gear changes, delayed engagement, and the dreaded check engine light. This genuine GM T42 Transmission Control Module, part number 24243901, is the definitive solution to restore the smooth, responsive performance your vehicle was designed for. As the electronic brain of your automatic transmission, the TCM is responsible for managing shift points, torque converter clutch lockup, and line pressure, making its proper function absolutely critical for both drivability and longevity.
When the original module fails, it can lead to a cascade of problems that can be misdiagnosed as major mechanical failures. Before considering a costly transmission rebuild, it’s essential to properly diagnose the electronics. This replacement module arrives pre-programmed to your SSR’s specific Vehicle Identification Number (VIN), ensuring a seamless, plug-and-play installation without the need for an expensive trip to the dealership for programming. It’s designed to communicate perfectly with your vehicle’s Powertrain Control Module (PCM) and other systems right out of the box.
From the Diagnostic Bay
We had a 2006 SSR roll into the shop with a complaint of erratic shifting and a persistent transmission warning light. The owner was worried he needed a new transmission. After pulling the codes, we saw a P0700 and a few solenoid circuit faults. Instead of jumping to conclusions, we checked the TCM connectors for corrosion—they were clean. We knew that the T42 modules on these platforms can develop internal faults that cause these exact symptoms. We installed one of our VIN-programmed modules, cleared the codes, and took it for a test drive. The shifts were instantly crisp and correct. The customer was thrilled to solve a ‘transmission’ problem for a fraction of the cost and time.
Diagnosing a Faulty 2005-2006 SSR TCM
The Transmission Control Module is a complex computer, and its failure can manifest in various ways. If you’re experiencing any of the symptoms below, your TCM is a likely suspect. Ignoring these signs can lead to premature wear on your transmission’s mechanical components, such as clutches and bands, turning a relatively simple electronic fix into a major mechanical repair. This 2005-2006 SSR TCM is engineered to resolve these issues and prevent further damage.
Common Symptoms of TCM Failure
- ✔ Harsh or Erratic Shifting: Gears may slam into place, or the vehicle may hunt for the correct gear.
- ✔ Delayed Engagement: A noticeable pause when shifting from Park into Drive or Reverse.
- ✔ Stuck in Limp Mode: The vehicle may refuse to shift out of a single gear (often 2nd or 3rd) to protect the transmission.
- ✔ Warning Lights: Illumination of the Check Engine Light or a specific transmission warning indicator on your dash.
- ✔ Diagnostic Trouble Codes (DTCs): Common codes include P0700 (Transmission Control System Malfunction) and various solenoid-specific codes (e.g., P0751, P0756).
- ✔ Poor Fuel Economy: Inefficient shifting and torque converter operation can lead to a sudden drop in MPG.
- ✔ Complete Loss of Shifting: In severe cases, the transmission may not shift at all.
The Plug-and-Play Advantage
What sets our modules apart is the crucial VIN programming service included with your purchase. A generic, unprogrammed module from a parts store or salvage yard will not work correctly. It must be coded to your vehicle’s specific configuration, including tire size, gear ratio, and engine type. Our process handles this for you. We load the latest GM-authorized software and calibrations onto the module using your VIN, so when it arrives, you simply install it, connect the harnesses, and you’re ready to go. This saves you hundreds of dollars in dealership fees and eliminates vehicle downtime.
This module is a direct replacement for a wide range of GM vehicles using the T42 controller and 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E. It is interchangeable with numerous service numbers, including 24252114, 24234503, 24242391, and others, ensuring broad compatibility. Whether you’re working on your SSR or another vehicle in the GM family, this part provides a reliable, high-quality solution. With a one-year warranty and no core charge, you can purchase with complete confidence. Get your 2005-2006 SSR TCM today and get back on the road with a transmission that performs as it should.
Frequently Asked Questions
What does a Transmission Control Module do in my SSR?
The TCM is the dedicated computer for your automatic transmission. It receives data from various sensors (like vehicle speed, throttle position, and engine RPM) and uses this information to control shift solenoids, regulate hydraulic pressure, and manage the torque converter clutch. This ensures smooth, efficient, and timely gear changes.
Why is VIN programming necessary for this TCM?
VIN programming loads your vehicle’s specific software and calibration files onto the module. Every vehicle has slight differences in its factory setup (like axle ratios or tire sizes). Programming ensures the TCM makes the correct decisions for your exact vehicle, guaranteeing optimal shift quality, fuel economy, and overall performance without any conflicts.
Is this module difficult to install on a 2005-2006 SSR?
Installation is straightforward for someone with basic mechanical skills. On the SSR, the TCM is located on the front left-hand frame rail. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. The entire job typically takes less than an hour.
Will this part fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the Check Engine Light to be turned on. While this module can resolve the underlying issue causing the P0700, it’s important to have the specific transmission codes read to confirm the diagnosis. Often, a faulty TCM is the root cause of the codes that trigger a P0700.
Do I need to return my old part?
No, there is no core charge for this part. You can keep your old module, which saves you the time, cost, and hassle of shipping it back.
