2006-2014 GMC Savana 2500 Transmission Control Module (TCM) 24243901 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Frustrated by your GMC Savana 2500 suddenly slipping into limp mode during a heavy haul? You’re not alone—many van owners face this when the transmission control module starts failing, leading to erratic shifts and warning lights. What happens when your 2006-2014 GMC Savana 2500 transmission won’t upshift properly? It often points to a faulty TCM like part 24243901, which we’ve pre-programmed to your VIN for seamless replacement.

This OEM-spec GM T42 TCM restores precise control over gear shifting, torque converter operation, and diagnostic functions in 4-speed automatics such as the 4L60E or 4L80E. It fits a range of GM vehicles from 2006-2014, including Chevrolet Express, GMC Sierra, and more, with interchangeable numbers like 24252114, 24234503, and others.

Common Issues & How This Fixes Them

Over my 20+ years diagnosing GM vans, I’ve handled hundreds of Savana 2500 cases where heat from constant cargo loads causes TCM circuit degradation. This leads to symptoms like harsh shifting or delayed gear engagement, often triggering DTCs such as P0700 or P0750.

Drivers report vehicles stuck in 2nd or 3rd gear—limp mode—to protect the transmission, but it kills efficiency and risks overheating. Intermittent no-shifts or slipping can drop fuel economy by 10-15%, based on shop data from similar failures.

Replacing with our VIN-programmed TCM resolves these by recalibrating solenoid controls and lockup timing. It prevents solenoid codes and restores smooth operation, potentially saving $500+ on unnecessary rebuilds. In one scenario, a fleet owner avoided downtime by swapping this module, getting back to deliveries without dealership visits.

Easy Installation Guide

Swapping the TCM in your 2006-2014 GMC Savana 2500 takes about 20-30 minutes. Locate it on the right-hand engine compartment side. Start by disconnecting the battery to clear codes safely.

Remove the old module, install the new one, and reconnect. Use an OBD-II scanner to erase any lingering DTCs. For GM vehicles, a theft deterrent relearn is rare but if no-start happens post-install, cycle the key: Turn to ON for 10 minutes, off for 30 seconds, repeat three times.

This straightforward process avoids core charges; keep your old part. It empowers DIYers to fix “how to replace TCM in GMC Savana 2500” queries without pro help, saving time and money.
