The 6 speed transmission that comes standard with the F150 3.7L V6 is a big improvement in driver controls over passed 4 speed transmissions. However, there are still some major benefits to be had recalibrating normal daily shift strategies. We have noticed that while in normal everyday mode that the transmission will move into 6 gear really quickly around town with speeds as low as 35-38 mph this really lugs the engine and when trying to accelerate there is a pretty good delay to either downshift or accelerate. We can correct this by moving some shift strategies patterns around in all gears especially in 5th and 6th gears. In the tow/haul mode the Factory strategies in are very inefficient. 6th gear is useless under 60 mph. In the 3.7L V6 there is little engine braking in stock form while in tow/haul mode. Coasting or slowing down the downshifts don’t command soon enough to slow truck down and downshifts don’t command soon enough to keep the RPM’s up in torque range and when back in throttle multiple down shifts seem to occur. Gears 2nd, 3rd and 4th are the gears the truck likes to run at under 60 mph towing 5000lb but its in 6th gear at 50 mph lugging engine. Once RPM’s builds to 3000 plus the truck pulls like a champ but factory strategies keep RPM’s low. For owners of F150 3.7L V6 going to tow trailers at 5000 lbs the factory strategies will hunt all over the place in tow/haul mode. We have recalibrated tow/haul mode strategies that enhances keeping the engine RPM’s elevated to take advantage of the torque band in this 3.7L V6 less downshifting and taking advantage of gears 2nd, 3rd and 4th more. All of our calibrations have this new tow/haul strategy except economy mode calibrations.
