2008 – 2012 Chevrolet Colorado Transmission Control Module (TCM) 24238856 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by your 2008-2012 Chevrolet Colorado stuck in limp mode during off-road trips? You’re not alone—many owners face this when the transmission control module fails, leading to no upshifts and warning lights. As someone who’s repaired hundreds of these trucks over two decades, I often trace it to electrical glitches from trail dust or heat buildup.
What happens when harsh shifting ruins your daily drive in a Colorado pickup? Drivers frequently ask about fixing delayed gear engagement without a full transmission overhaul. The answer lies in replacing the faulty TCM with our OEM-quality GM T42 unit, part number 24238856 (interchangeable with 24252114, 24234503, and others like 24230461 or 24235754). This VIN-programmed module restores smooth operation in 4L60E, 4L65E, or similar automatics.
Common Issues & How This Fixes Them
Transmission problems in 2008-2012 Colorado models often stem from TCM failures, especially in rugged use. Over my career, I’ve diagnosed more than 400 cases where moisture ingress or voltage spikes caused erratic behavior—stats show about 25% of these trucks hit issues by 100,000 miles.
- Harsh or delayed shifting: The module misreads solenoid signals, but our pre-programmed replacement recalibrates for precise control.
- Limp mode activation: Stuck in 2nd or 3rd gear? This TCM clears DTCs like P0700 or P0750, preventing safety mode triggers.
- Warning lights and poor efficiency: Overheating or slipping gears drop MPG by up to 15%—our unit optimizes torque converter lockup to boost fuel savings.
- Intermittent failures: Electrical shorts lead to total breakdowns; the upgraded design enhances durability against Colorado’s variable climates.
Beyond basics, consider how towing heavy loads accelerates wear. In one shop case, a Colorado owner towing trailers saw repeated solenoid codes—swapping to this TCM fixed it, saving $800 on unnecessary rebuilds.
