Restore the Signature Performance of Your Chevrolet SSR
If you’re experiencing frustrating and unpredictable shifting in your 2005-2006 Chevrolet SSR, a failing Transmission Control Module (TCM) is the likely culprit. As the electronic brain of your 4L60E or 4L65E automatic transmission, the TCM dictates every gear change, manages torque converter lockup, and monitors system health. When it fails, the unique driving experience of your SSR is compromised. This OEM-quality T42 TCM, part number 24239926, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a direct, hassle-free installation that restores the smooth, responsive shifting you expect.
From the Diagnostic Bay: Solving an SSR’s Ghostly Glitches
A customer brought in his 2006 SSR with a really baffling issue. He said it would intermittently refuse to shift out of 2nd gear, but only after driving for 20+ minutes. The check engine light was on, but the codes were for multiple shift solenoids—a classic wild goose chase. In my 20 years of experience, when you see multiple, seemingly unrelated solenoid codes pop up at once, the problem is rarely the solenoids themselves. It’s almost always the module commanding them. We swapped in a VIN-programmed 2005-2006 SSR TCM, cleared the codes, and took it for a long test drive. The shifting was perfect, and the ghost codes never returned. It’s a textbook example of how a faulty TCM can mimic other failures, and why a reliable replacement is key.
Is Your SSR’s Transmission Acting Up? Check for These Signs.
A failing TCM can manifest in several ways. If you notice any of the following, it’s time to diagnose your module. Overlooking these symptoms can lead to more significant transmission damage down the road.
- ✔ Harsh, slamming shifts or delayed gear engagement.
- ✔ Vehicle is stuck in “limp mode,” often refusing to shift past 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), P0750-series (Shift Solenoid), or other communication errors.
- ✔ Poor acceleration and a noticeable drop in fuel economy.
- ✔ The transmission feels like it’s slipping between gears or won’t upshift at all.
