Restore Flawless Shifting to Your 2005-2006 Chevrolet SSR
Is your Chevrolet SSR suffering from erratic shifting, delayed gear engagement, or getting stuck in limp mode? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change and ensuring smooth, efficient operation. When it fails, it can turn your driving experience into a frustrating and unpredictable ordeal. This genuine quality T42 TCM, service part number 24235753, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
Diagnosing a Faulty Transmission Control Module
A failing TCM can manifest in various ways, often mimicking mechanical transmission problems. Before condemning your transmission’s internal components, it’s crucial to consider the module itself. Your SSR might be exhibiting symptoms like sudden, harsh downshifts when coming to a stop, a noticeable lag when shifting from Park to Drive, or the unnerving experience of the transmission refusing to shift out of a single gear. You’ll likely see a Check Engine Light or a dedicated transmission warning light on your dashboard, accompanied by diagnostic trouble codes (DTCs) such as P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0750-P0758). Ignoring these signs can lead to decreased fuel economy, excessive heat buildup in the transmission, and potentially irreversible mechanical damage.
From the Diagnostic Bay
We recently had a 2006 SSR in the shop with classic symptoms: harsh 1-2 shifts and occasionally getting stuck in 3rd gear. The owner had already spent a significant amount replacing two shift solenoids based on some generic advice, but the problem persisted. A quick scan showed a P0700 code and intermittent communication errors with the TCM. We installed one of our VIN-programmed T42 modules, and within a 30-minute installation and a short test drive, the truck was shifting as smoothly as it did from the factory. It’s a powerful reminder that diagnosing the electronic controller first can save hundreds of dollars and hours of unnecessary mechanical work.
Key Features of Your 2005-2006 SSR TCM
- ✔ VIN-Programmed for Your SSR: This isn’t a generic, one-size-fits-all module. We program it specifically to your vehicle’s VIN before shipping, loading the latest GM software and calibrations. This ensures perfect communication with your vehicle’s other computers and eliminates the need for expensive dealership programming.
- ✔ Direct Plug-and-Play Solution: With the programming handled, installation is straightforward. Simply locate the old module on the front left-hand frame of your SSR, disconnect the battery, swap the units, and reconnect. The process is simple for any competent DIY mechanic.
- ✔ Resolves Common Shifting Issues: Effectively corrects problems like harsh shifting, slipping between gears, failure to upshift or downshift, and delayed engagement, restoring the crisp, responsive performance you expect.
- ✔ Clears Persistent Trouble Codes: A new, properly functioning TCM is often the key to permanently clearing stubborn transmission-related DTCs that keep your check engine light illuminated.
- ✔ OEM-Quality Construction: Built to meet or exceed original equipment standards for durability and performance, ensuring a long service life and reliable operation under all driving conditions.
- ✔ No Core Charge Required: Keep your old part without the hassle or expense of a core return. This simplifies the process and saves you money.
Simple Installation Process
Replacing the TCM on your 2005-2006 SSR is a manageable task. The module is located on the front left-hand side of the vehicle’s frame. Always begin by disconnecting the negative battery terminal to prevent electrical shorts and to help reset the vehicle’s computer systems. After locating the old TCM, carefully disconnect the electrical harnesses and unbolt it from its mounting bracket. Install the new module in its place, reconnect the harnesses securely, and then reconnect the battery. After installation, it’s a good practice to use a basic OBD2 scan tool to clear any stored fault codes. A short test drive will allow the module to complete its adaptation process with the transmission.
This T42 TCM is also a direct replacement for a wide array of other GM vehicles and interchanges with part numbers such as 24252114, 24234503, 24230461, 24234274, 24235340, and many more, making it a versatile and proven component across the GM family of trucks and cars from that era.
Frequently Asked Questions
What is a T42 TCM and what does it do?
The T42 TCM is a specific type of Transmission Control Module used by General Motors in the mid-2000s. It acts as the computer for your 4-speed automatic transmission (like the 4L60E/4L65E in your SSR), controlling shift points, line pressure, and torque converter lockup to ensure optimal performance, fuel economy, and smoothness.
Is this a plug-and-play part for my 2005 SSR?
Yes. Because we pre-program the module to your vehicle’s specific VIN number before it ships, it is a true plug-and-play solution. You will not need to take your vehicle to a dealership for additional programming after installation.
Will this 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 be turned on. While this module can resolve the root cause that triggers a P0700, it’s essential to have the specific transmission codes read to confirm the TCM is the likely point of failure. It often resolves issues related to solenoid circuits and internal controller faults.
Do I need to send my old module back?
No, there is no core charge for this part. You can keep your old module, which simplifies the purchasing and installation process for you.
Where is the TCM located on a 2005-2006 Chevrolet SSR?
On the 2005-2006 SSR, the Transmission Control Module is typically mounted on the front left-hand (driver’s side) frame rail. Always confirm the location on your specific vehicle before beginning work.
