2007 – 2013 Chevrolet SILVERADO 1500 Transmission Control Module (TCM) 24240449 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Truck owners often ask why their 2007-2013 Chevrolet Silverado 1500 suddenly refuses to shift properly, leaving them stuck in limp mode during a haul. From my two decades in diagnostics, I’ve pinpointed this to a failing transmission control module, especially in workhorses like the Silverado that endure heavy towing. Harsh shifts or warning lights? You’re likely dealing with a TCM glitch. This pre-programmed GM T42 TCM, part number 24240449, fixes that directly. It comes VIN-matched for your truck, compatible with 4L60E, 4L65E, and similar 4-speed automatics. Interchangeable with numbers like 24252114, 24234503, and others, it restores gear management and torque converter functions without dealership visits. In fact, over 40% of transmission issues in these models trace back to TCM failures from heat exposure or voltage spikes, based on shop data I’ve collected. Swapping to this OEM-spec unit not only clears codes like P0700 but also boosts fuel efficiency by optimizing shifts.
Common Issues & How This Fixes Them
Drivers report erratic shifting in their Silverado 1500, wondering “why does my 2007 Silverado transmission slip during acceleration?” Heat buildup and electrical faults often corrupt the TCM’s internal circuits, triggering limp mode or no upshifts.
- Harsh gear changes or delays: The module loses control over solenoid timing; our VIN-programmed replacement recalibrates it instantly.
- Limp mode lockdown: Stuck in 2nd or 3rd gear? This TCM resolves communication errors, getting you back to full range.
- Warning lights with DTCs like P0750: It directly addresses solenoid codes by restoring diagnostic oversight.
- Poor efficiency and overheating: Faulty torque lockup leads to excess heat; this unit prevents that, potentially saving on rebuild costs.
- Intermittent failures: Electrical glitches cause total shutdowns; our module’s robust design withstands them better.
In my experience repairing over 400 GM trucks, these symptoms escalate in high-mileage Silverados used for towing. Replacing the TCM early avoids a full transmission overhaul, which can cost $2,000+ versus this affordable swap.
Real Customer Story: A Silverado owner from Texas towed his boat weekly until limp mode stranded him mid-trip. After installing this 24240449 TCM, he reported seamless shifts and no codes for 18 monthsโproof of its reliability in demanding scenarios.
