Restore Your SSR’s Shifting Performance and Drivability
Is your 2005-2006 Chevrolet SSR suffering from harsh shifting, getting stuck in gear, or throwing transmission codes? A faulty Transmission Control Module (TCM) is often the culprit. As the electronic brain of your automatic transmission, the TCM dictates every gear change and torque converter operation. When it fails, it can make your unique SSR feel unpredictable and unreliable. This direct-replacement T42 TCM, part number 24235754, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play fix.
A Technician’s Notebook: The Misleading Solenoid Code
A customer brought in a 2006 Chevy SSR with a classic complaint: erratic shifting and a check engine light. The scanner pulled a P0752 code, pointing to a ‘Shift Solenoid A Stuck On’ condition. The last shop had already replaced the solenoid inside the transmission pan, but the problem persisted. This is a scenario I’ve seen over a hundred times with these GM T42 modules. The internal drivers on the TCM’s circuit board weaken over time from heat and vibration, failing to send the correct voltage to the solenoids. The result? The computer flags the solenoid, but the real problem is the module itself. Installing a new, correctly programmed 2005-2006 SSR Transmission Module resolved the issue instantly, saving the customer from a costly and unnecessary transmission teardown.
Is Your SSR Showing These Telltale Symptoms?
A failing TCM can manifest in several ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Harsh, jerky, or delayed gear shifts that disrupt your drive.
- ✔ Vehicle enters “limp mode,” often stuck in 2nd or 3rd gear.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700 (Transmission Control System Malfunction), U0101, or various solenoid-specific codes (P0750-P0758).
- ✔ A noticeable drop in fuel economy or the transmission overheating.
- ✔ The transmission fails to shift up or down, or seems to slip between gears.
DIY Installation: A Straightforward 30-Minute Fix
One of the best features of this module is its simple installation. Because we program it to your VIN before shipping, you don’t need a trip to the dealer or any special scan tools for setup. For the 2005-2006 SSR Transmission Module, the location is typically on the front left-hand side of the frame.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and help reset the system.
- Locate the Module: Find the old TCM on the front LH frame rail of your SSR. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully unclip the wiring harnesses. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place and securely reconnect the wiring harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. While not always necessary, clearing any old codes with a basic OBD-II scanner is good practice.
