The 10 speed transmission that comes standard with the 2020 F250- F350 7.3L V8 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. FACT ! Ford uses the same shift output strategy for all of these trucks no matter what final gear ratio is in the truck. So if you have a 3.55 or a 4.30 geared truck they will shift different using this strategy from Ford. We can be very specific on your vehicle. Below are some specific examples of what great calibrations can do for a vehicle.
NORMAL MODE: (For everyday on-road driving duties, normal mode is a perfect balance of excitement, comfort and convenience). 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. We have corrected this by raising (slightly) these gears to eliminate the lugging or sluggishness. The Ford stock pattern is also skip shifting in normal mode most of time its 1-3 3-5 and the goofy one’s are 2-4 4-6 shifts. We have corrected this by moving some shift strategies patterns around and we are using a 1-3 3-5 skip at light throttle only (2-4 & 4-6 are eliminated in this mode) but once at wide open throttle you will use all the gears just like factory. 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 7.3L V8, while maintaining great fuel economy and power to accelerate when needed.
TOW/HAUL MODE: (For improved transmission operation when towing a trailer or a heavy load. This mode moves upshifts to higher engine speeds to reduce frequency of transmission shifting. This mode also provides engine braking in all forward gears, which slows your vehicle , particularly on descending grades. The amount of downshift braking varies based on the amount you press the brake pedal.) 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.
DEEP SNOW / SAND MODE: Our calibrations leave this mode just like stock. We have made no adjustments here.
ECO MODE: (For efficient driving. This mode helps deliver maximum fuel efficiency and helps increase driving range.) Our calibrations leave this mode just like stock. We have made no adjustments here.
SLIPPERY MODE: (For less than ideal road conditions such as snow or ice covered roads. Use this mode for crossing terrain where loose , wet or slippery material covers a firm surface. Slipper Mode lowers throttle response and optimizes shifting for slippery conditions.) Our calibrations leave this mode just like stock. We have made no adjustments here.
ROCK CRAWL MODE (Tremor Package): (For optimum rock-climbing ability. Rock crawl mode prompts you to put your vehicle in 4×4 Low. Rock Crawl mode optimizes the throttle and transmission response to provide you additional control of your vehicle.) Our calibrations leave this mode just like stock. We have made no adjustments here.
