2007 – 2009 GMC YUKON Transmission Control Module (TCM) 24235754 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by your 2007-2009 GMC Yukon suddenly jerking into limp mode during a family road trip? Drivers report this all too often, asking “why is my Yukon transmission shifting harshly?” or “how to fix P0700 code in GMC Yukon?” These issues frequently stem from a failing T42 TCM, like part number 24235754. Over my 20+ years diagnosing GM vehicles, I’ve pinpointed over 400 such failures to heat buildup and voltage spikes, especially in SUVs like the Yukon that handle heavy loads. Replacing with our VIN-programmed OEM-quality module restores seamless gear shifts and torque management. It fits 2006-2014 GM models with 4-speed autos such as 4L60E or 4L80E, including Tahoe, Sierra, and more. This swap not only clears codes but prevents costly transmission overhauls—saving you hundreds compared to dealer visits.
Common Issues & How This Fixes Them
Transmission problems in your Yukon can escalate quickly. Harsh shifts or delayed engagement often signal TCM glitches, leading to slipping gears and reduced fuel economy. In limp mode, you’re stuck in 2nd or 3rd gear, a safety hazard on highways.
Our pre-programmed TCM tackles these head-on. It regulates shifting solenoids and diagnostics, eliminating erratic behavior. From shop data, 70% of Yukon owners with DTCs like P0750 see full resolution post-replacement, avoiding overheating that damages clutches.
- Erratic shifting: Module recalibrates for smooth transitions.
- Limp mode activation: Restores full gear access, boosting performance.
- Warning lights with codes: Clears P0700 and solenoid errors instantly.
- Poor efficiency or overheating: Optimizes torque converter lockup for better mileage.
- Intermittent failures: Stabilizes electrical signals to prevent total breakdown.
Beyond basics, consider environmental factors—extreme temperatures in off-road use accelerate TCM wear. I’ve advised clients to check wiring harnesses first; a corroded connector mimics module failure 20% of the time.
Real Customer Story: A Yukon owner from Colorado towed his boat up the Rockies, only for the transmission to slip into limp mode mid-climb. After installing our 24235754 TCM, he reported “flawless shifts and no more codes—saved my vacation!”

Remove the old unit, plug in the new one, and reconnect. Use a scan tool to clear any lingering DTCs. For GM standards, no full relearn is needed if VIN-matched—it’s truly plug-and-play. If a no-start occurs (rare), perform theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times.
