Purpose-built transmission tuning for 2015–2016 Ford Super Duty trucks running a Cummins common rail engine with the factory 6R140 transmission. This calibration is designed to seamlessly integrate Cummins power delivery with Ford’s transmission strategy—delivering OEM-level drivability with performance-focused refinement.
This tuning eliminates common swap issues and restores full factory functionality, including no dash warning lights, fully operational SelectShift, and Tow/Haul mode working exactly as intended.
Shift behavior is significantly improved with firmer, more controlled shifts and revised shift scheduling tailored specifically to the torque curve and operating characteristics of a Cummins engine. The result is smoother power transfer, better gear holding under load, and improved overall drivability compared to stock Ford logic.
Extensively developed and validated through over one year of real-world testing with 15,000+ miles of proven, problem-free operation, this solution delivers reliability you can trust in both daily driving and heavy towing applications.
Designed specifically for common rail Cummins applications, this tuning does not require an aftermarket torque converter, keeping your build simpler and more cost-effective while maintaining excellent performance.
