Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.
For F350, F450, F550 and F600
Chassis Cab Vehicles
Your transmission could reduce the load
on the engine when the vehicle stops, and
the gear selector is in drive (D) to reduce
fuel consumption and emissions. The
transmission resumes operation when you
release the brake. This feature activates
when the transmission is sufficiently
warmed, and the vehicle is on a level slope.
Brake-Shift Interlock WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible.
Note: Do not drive your vehicle until you
verify that the brake lamps are working.
Your vehicle comes with brake-shift
interlock that prevents the gearshift lever
from moving from park (P) when you
switch the ignition on but have not pressed
the brake pedal.
If you cannot move the gearshift lever out
of the park (P) position when the ignition
is on and the brake pedal pressed, a
malfunction could have occurred. It is
possible that a fuse has blown, or your
vehicle ’s brake lamps are not operating
properly. See
Fuse Specification Chart
(page 329).
If you do not have a blown fuse and the
brake lamps are working properly, the
following procedure allows you to move
the gearshift lever from park (P):
1. Apply the parking brake. Switch the ignition key to 1 - 0, then remove the
key.
See Starting and Stopping the
Engine (page 168).
2. Move the steering column to the full down and full rearward position,
toward the driver seat.
3. Remove the gearshift lever boot.

FUSE SPECIFICATION CHART
Engine Compartment Fuse Box
WARNING: Always disconnect the
battery before servicing high current
fuses. WARNING:
To reduce risk of
electrical shock, always replace the
cover to the power distribution box
before reconnecting the battery or
refilling fluid reservoirs. The engine compartment fuse box is in the
engine compartment. It has high-current
fuses that protect your vehicle's main
electrical systems from overloads.
If you disconnect and reconnect the
battery, you need to reset some features.
See Changing the 12V Battery
(page 368).
Replace fuses with the same type and
rating. See Changing a Fuse (page 335). 329
