2007.5-2010 Duramax AMDP EFI Live Allison Transmission Tuning

Unlock the full potential of your Allison 1000 with AMDP Custom Transmission Tuning. While factory tuning is designed for the average commuter, AMDP recalibrates your TCM via EFI Live to handle the increased horsepower and torque of a tuned Duramax. By optimizing shift points and converter lockup schedules, this tuning ensures your truck is always in the right gear for the load, whether you’re daily driving or towing heavy.

The key to longevity in these transmissions is line pressure. AMDP tuning increases internal line pressure to provide a much firmer "clamping force" on the clutch packs, significantly reducing slippage and heat buildup under high-load conditions. The result is a truck that feels more responsive, shifts more predictably, and stays cool when the work gets tough.

Part Number: 

• Increased Line Pressure: Provides greater clamping force to prevent clutch slippage under high torque.
• Optimized Shift Points: Adjusted for better power delivery and drivability across all throttle positions.
• Adjusted Converter Lockup: Keeps the torque converter locked in the right spots to lower fluid temps and improve efficiency.
• Improved Drivability: Eliminates the "hunting" for gears common in factory-tuned Allison transmissions.
• Better Towing Performance: Optimized shift schedules help maintain momentum while pulling heavy grades.
• Seamless Integration: Designed to work perfectly alongside AMDP engine tuning for a complete performance package.
