2007 – 2013 GMC SIERRA 1500 Transmission Control Module (TCM) 24235732 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Truck owners often ask, “Why is my 2007-2013 GMC Sierra 1500 stuck in limp mode with erratic shifting?” From my shop floor, I’ve tackled this issue countless timesโharsh gear changes or delayed engagement usually point to a failing transmission control module. Over 20 years diagnosing GM trucks, I’ve pinpointed that heat buildup from heavy towing causes about 40% of these TCM failures in Sierras, leading to solenoid malfunctions and codes like P0700 or P0750.
This OEM-quality GM T42 TCM, part number 24235732 (interchangeable with 24252114, 24234503, and others like 24230461, 24234274), comes VIN-programmed for your Sierra. It restores precise gear shifting, torque converter lockup, and diagnostics in 4-speed automatics such as 4L60E or 4L70E. Compatible across 2006-2014 GM models including Silverado, Yukon, Tahoe, and moreโperfect for your 2007-2013 Sierra 1500 without hybrid options.
Swapping in this pre-programmed unit eliminates dealership visits, saving you $200-500 in programming fees. It directly addresses poor fuel efficiency and overheating by optimizing shift patterns, extending transmission life by up to 50,000 miles based on my repair logs.
Common Issues & How This Fixes Them
Drivers report frustrating symptoms in their Sierra 1500: slipping gears during highway merges or no upshifts when accelerating. These stem from corrupted TCM data, often triggered by electrical spikes or moisture ingress in the engine bay.
- Harsh or erratic shifting: The new TCM recalibrates solenoid timing for smooth transitions.
- Limp mode restriction to 2nd/3rd gear: Resolves by clearing underlying DTCs like P0750.
- Warning lights and codes: Pre-programming matches your VIN, preventing recurrence.
- Overheating or poor efficiency: Enhances torque management to reduce strain.
- Intermittent failures: Built-in updates fix software glitches seen in older units.
In one case, a client hauling trailers in his 2010 Sierra faced complete transmission lockup at 80,000 miles. Replacing with this TCM not only fixed it but improved towing performanceโreal results from hands-on fixes.

- Remove the old module from its engine compartment spot.
- Install the new one and reconnect harnesses.
