Protect Your Allison: AMDP EFILive TCM Tuning for LML Duramax
Don't let a slipping Allison transmission ruin your build. When you add serious horsepower to your 2011-2016 GM 6.6L LML Duramax, your factory transmission calibrations simply cannot keep up with the extra torque. The AMDP EFILive TCM Tune File is the ultimate digital upgrade designed to deliver crisp, firm shifts and keep your powertrain highly reliable under heavy towing and competition loads.
By commanding higher line pressure, this custom AMDP calibration forces your clutch packs to clamp down harder, drastically reducing the slip that causes premature wear and catastrophic transmission failure. It automatically adjusts your shift points to keep your Duramax in its optimal power band, giving you vastly improved daily drivability, throttle response, and power delivery to the ground.
⚠️ IMPORTANT: This is a digital calibration package. Please checkout using a valid email address. Your files are pushed via the Cloud, and we will email you the exact instructions to link your vehicle within 24-48 business hours. Ensure your exact 17-digit VIN is entered correctly above.
Maximize Your Build
Pro Tip: This TCM tune pairs perfectly with AMDP's EFILive Custom Engine (ECM) Tune Files. Running AMDP for both your engine and transmission ensures your shifting strategy is perfectly synchronized with your new horsepower curve for the most reliable towing capability possible.
