SFT Transmission Tune Features:

It's everything the EcoDiesel's Transmission should be:

- Shifts sooner (like a diesel is supposed to)

- Instant downshifts to pass people. No delay!

- Holds gears longer without downshifting

- Gets into 8th gear sooner for better economy

- Torque converter locks up faster/sooner (less slipping means more power to wheels which means less power loss, less heat and less clutch wear... prolongs the transmission's life)

- 2nd gear rolling stops

- No more banging into 2nd or 1st coming to a stop then accelerating 

-Tow / haul mode improved. 8 gear towing and not constantly revving in 6th / 7th Gear. 

- Gradually shifts from 8th to 1st during deceleration, significantly reducing driver braking input.
