Description
Description
The DIESELR EFI Live Transmission Tune File (2013–2018 Cummins 6.7L AISIN) is purpose-built for Cummins owners who need their transmission to keep pace with serious ECM tuning. Stock AISIN programming is notorious for short-shifting, lugging, and sluggish response. This calibration fixes those issues and delivers the transmission performance your truck should have had from the factory.
With refined shift logic, the tune keeps your 6.7L Cummins in its ideal torque band, eliminating the 1000 RPM lugging problem and improving drivability across all conditions. Gear changes are sharper and more predictable, throttle response feels direct, and towing becomes more controlled with stronger gear holding under heavy loads.
Key advantages:
- Direct EFI Live flash with AutoCal device
- Refined shift points for better acceleration and pulling power
- Stronger torque management to match aggressive ECM tunes
- Improved towing confidence with smoother power delivery
- Essential for trucks with bigger turbos, larger tires, or performance upgrades
- Keeps the Cummins torque curve fully available at the wheels
DIESELR transmission tuning is proven, tested, and trusted by diesel truck owners across North America. Whether you daily drive, tow heavy, or push big builds, this file makes your AISIN transmission perform at its best.
And with Dieselr’s industry-leading support, you’re backed by real experts who walk you through setup, flashing, and fine-tuning — no call centers, just mechanics and tuners who know your truck.
