Transmission By moving the gearshift lever from the D (Drive) position to the M (Manual) position you may now manually select the gear you desire. Only the current gear will be displayed. Press the + button or the - button to upshift or downshift. If the - button is pressed at a vehicle speed that would cause an engine overspeed, the requested gear will flash then disappear and the transmission will remain in the current gear. Recommended shift speeds Upshift according to the following chart: Upshifts when accelerating (recommended for best fuel economy) Shift from: 1-2 2-3 3-4 4-5 5-6 Gasoline engines 15 mph (24 km/h) 25 mph (40 km/h) 40 mph (64 km/h) 45 mph (72 km/h) 50 mph (80 km/h) Diesel engines 12 mph (19 km/h) 19 mph (31 km/h) 26 mph (42 km/h) 34 mph (55 km/h) 46 mph (74 km/h) In order to prevent the engine from running at too low an RPM, which may cause it to stall, SelectShift will still automatically make some downshifts if it has determined that you have not downshifted in time. Although SelectShift will make some downshifts for you, it will still allow you to downshift at any time as long as the SelectShift determines that the engine will not be damaged from over-revving. SelectShift will not automatically upshift, even if the engine is approaching the RPM limit. It must be shifted manually by pressing the + button. Note: Engine damage may occur if excessive engine revving is held without shifting. Automatic Transmission Adaptive Learning This feature is designed to increase durability and provide consistent shift feel over the life of the vehicle. A new vehicle or transmission may have firm shifts, soft shifts or both. This operation is considered normal and will not affect function or durability of the transmission. Over time, the adaptive learning process will fully update transmission operation. Additionally, whenever the battery is disconnected or a new battery installed, the strategy must be relearned. Brake-Shift Interlock WARNINGS Do not drive your vehicle until you verify that the brake lamps are working. 150 Super Duty (), enUSA
