The 10 speed transmission that comes standard with the F250- F350 6.7L is a big improvement in driver controls over prior 6 speed transmissions. However, there are still some significant benefits to be had re-calibrating normal daily shift strategies. With the 2020 having many modes, we will just talk about the 2 most used modes here.

DAILY MODE    We have noticed that while in normal everyday mode that the transmission will move into 8th,9th, 10th gears really quickly around town with speeds as low as 42 mph this really lugs the engine and when trying to accelerate there is a pretty good delay to either downshift or accelerate. Also Ford is skip shifting in normal mode as well.  We can correct this by moving some shift strategies patterns around in all gears. Our calibrations will have emphasis on shifting at the right mph and rpm as to take advantage of the low torque that is available from the 6.7L while maintaining great fuel economy and power to accelerate when needed.

TOW/HAUL Mode   Coasting or slowing down the downshifts don’t command soon enough to keep the RPM’s up in torque range and when back in throttle multiple downshifts may occur. so a quick downshift for braking is required for owners that are going to tow heavy. We have re-calibrated tow/haul mode strategies that enhances keeping the engine RPM’s elevated to take advantage of the torque band which will require less downshifting by optimizing gears. We have also enhanced the down shift patterns to allow better engine braking with this V8 engine. All of our calibrations have this new tow/haul strategy except performance calibrations.
