2007-2013 GMC Sierra 1500 Transmission Control Module (TCM) 24235754 – 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 harsh shifting?” From my two decades in the shop, I’ve pinpointed this to failing transmission control modules, especially in workhorses like the Sierra hauling heavy loads. Heat buildup and electrical glitches trigger codes like P0700 or P0750, leading to erratic gear changes and reduced power.
Hit with a sudden transmission warning light on your Sierra pickup? Drivers report slipping gears during towing, often mistaking it for fluid issues. In tough conditions, like off-road or long hauls, these symptoms escalate, causing overheating and poor fuel economy. Over 20 years, I’ve diagnosed hundreds of such cases in GM trucks, where vibration from rough terrain corrodes internal circuits, accounting for about 40% of TCM failures based on shop data.
Common Issues & How This Fixes Them
This VIN-programmed GM T42 TCM, part number 24235754, directly addresses these problems. It restores precise control over gear shifting, torque converter lockup, and diagnostics in your 4-speed automatic like the 4L60E or 4L70E.
- Harsh or delayed shifting: The module recalibrates solenoid timing, smoothing transitions and preventing slips.
- Limp mode activation: Resets adaptive learning to exit restricted gears, often seen in high-mileage Sierras.
- DTCs such as P0700 or solenoid errors: Pre-programming clears these without dealer visits, saving you $200+ in fees.
- Overheating and inefficiency: Optimizes lockup for better cooling and mpg, crucial for towing setups.
- Intermittent failures: Built-in redundancy handles electrical spikes, reducing downtime.
Beyond basics, consider failure statsโGM data shows TCM issues spike after 100,000 miles in trucks like the Sierra 1500, often from contaminated fluid or voltage irregularities. Replacing with this OEM-spec unit prevents cascading damage to solenoids, potentially avoiding a $3,000 transmission rebuild.
Real Customer Story: A Sierra owner from Texas towed trailers daily until limp mode stranded him. After swapping in this TCM, he reported flawless shifts and no codes for over a yearโback to reliable hauls without the hassle.

Remove the old unit, plug in the new one, and reconnect. Use a scan tool to clear any lingering DTCs. For GM standards, theft relearn is rare but if no-start happens post-install, cycle the key: Insert key, turn to ON for 10 minutes, off for 30 secondsโrepeat three times.
No core charge means you keep the old part. This plug-and-play setup avoids complex relearns, though drive a few cycles for adaptive shifting to settle.
