PRE-TUNED REPLACEMENT A50 T14 TCM FOR 2011-2015 (LML) ALLISON TRANSMISSION

Upgrades the problematic A50 TCM in 2011-2015 Chevrolet Silverado and GMC Sierra 2500HD/3500HD LML Duramax trucks to the more reliable T14 model. This custom-tuned TCM improves shift changes, smooths operation, enhances acceleration, and provides quicker shifts. It prevents short-shifting in performance use, improves torque converter lock-up strategies, and increases clutch holding capacity with elevated line pressure. It can also improve MPGs. This pre-tuned TCM is VIN-programmed for 5-minute plug-and-play installation, requiring no dealer visits. It's an important upgrade for trucks with ECM tuning, larger tires, bigger turbos, or built transmissions.
