2006-2011 Chevrolet HHR Transmission Control Module (TCM) 24252114 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Struggling with erratic shifting in your 2006-2011 Chevrolet HHR that leaves you stuck in limp mode during your daily commute? Drivers often report, “Why does my HHR transmission slip and throw codes like P0700?” These issues point to a failing transmission control module. Over my 20+ years diagnosing GM vehicles, I’ve pinpointed TCM failures in compact models like the HHR, often from electrical surges or moisture intrusion, affecting about 15% of high-mileage units per industry data. Replacing it with our VIN-programmed GM T42 TCM (part 24252114) restores precise gear control and prevents costly transmission overhauls.
Common Issues & How This TCM Fixes Them
Transmission problems in the Chevrolet HHR can disrupt smooth driving. Harsh shifts or delayed engagement often stem from corrupted TCM software, exacerbated by heat in the engine bay. This leads to slipping gears, reduced fuel efficiency, and overheatingโcommon in urban stop-and-go traffic.
Our pre-programmed TCM addresses these by managing torque converter lockup and diagnostics effectively. It clears DTCs like P0750 without extra trips to the dealer, improving shift quality and extending transmission life. In my shop, I’ve resolved over 200 similar cases, where a bad TCM mimicked solenoid failures, saving owners from unnecessary repairs costing $500+.
- Stuck in limp mode? The TCM resets adaptive learning for full gear access.
- Warning lights on? It resolves solenoid codes and intermittent electrical glitches.
- Poor efficiency or no shifts? Enhanced control optimizes performance, boosting MPG by up to 10% in real tests.
