Enhance your transmission's durability and improve fuel efficiency with Ewalt’s Auto Tuning Transmission Tuning—an essential upgrade for tuned trucks with added torque.

As pioneers in offering transmission tuning for the latest Allison models, Ewalt’s Auto Tuning has continued to lead the way with cutting-edge solutions.

The optimized shift points eliminate the low RPM "lazy" sensation that forces drivers to jab the throttle for a downshift—an inefficient habit detrimental to fuel economy. Transmission tuning is crucial for vehicles with larger turbochargers, as it helps maintain engine RPM within the optimal range to align with the torque curve of the upgraded turbo.

Additionally, the refined torque converter lockup strategy ensures power is delivered to the ground more efficiently, reducing unnecessary slip in the torque converter. This not only enhances fuel efficiency but also decreases heat generation in typical "unlocked" conditions.

Finally, and perhaps most importantly, the increased line pressure significantly boosts the transmission's holding capacity by applying greater clamping force to the clutch packs. This provides tuned trucks or heavy-towing vehicles the reliability and confidence needed for long-term performance and enjoyment.
