2012 FORD F650 transmission

WARNING:If the red BRAKE warning lamp in the instrument
cluster remains illuminated after engine start up, this indicates a
system failure in the Full Power Brake System. Stop the vehicle safely
as soon as possible and seek service immediately.
Note:During normal driving the pump/motors may be heard
replenishing the accumulators; this is a normal function of the system.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, pull handle up until it
snaps into the locked position.
WARNING:Do not use the
gearshift selector in place of
the parking brake. Always set the
parking brake fully AND make
sure the gearshift selector is in R
(Reverse) for vehicles equipped
with manual transmission, P
(Park)(if equipped)or N
(Neutral) for vehicles with
automatic transmission. Use of
wheel chocks is also
recommended in hilly or off-road
usage.
WARNING:Unexpected and possible sudden vehicle movement
may occur if these precautions are not taken.
When the parking brake is out of adjustment, seek service immediately.

POWER PARK (PARKING BRAKE) OPTION (IF EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulically-released driveline parking brake. It is
controlled by a yellow, dash-mounted parking brake knob.
The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),
neutral (central), and release (in). The switch is spring-loaded to return
to the neutral (central) position after being pushed or pulled.
There is no visual indication at the knob that the park brake is applied or
released; check the instrument cluster. If the
light is illuminated,
the parking brake is applied.
Applying the parking brake
To apply the parking brake, pull the yellow, dash-mounted parking brake
knob. A red light (
) in the instrument cluster should illuminate
indicating that the parking brake has been successfully set.
Note:If the
light blinks and a warning chime sounds when the
control knob is pulled, the parking brake is not functioning properly;
seek immediate service from your dealer. Refer toParking brake
warning systemin this section.
Releasing the parking brake
Note:Read and understand the following steps and perform them
whenever you prepare to drive the vehicle.
Note:The parking brake does not disengage unless sufficient system air
pressure is available.
Automatic transmissions - dash-mounted push button (Allison
3000 Series) and steering column-mounted (Allison 2200 and 2500)

Air brake reservoir draining
WARNING:Failure to drain air brake reservoirs can result in a
reduction or loss of braking ability due to fluid accumulation in
the reservoir and/or possible freeze-up during cold weather.
Drain all the air brake reservoirs
daily, completely to 0 psi/kPa, by
opening the draincock at the ends
of the tanks (where accessible.
Pull-chains are used when the
drains are undercab or otherwise
inaccessible). Close draincock after
complete draining. Air tanks
equipped with automatic moisture
ejector valves may also be drained
manually as required to maintain a
dry air system. Contact your dealer if you are unsure of the air reservoir
locations or the draining procedure.
Parking brake
WARNING:Do not use the gearshift selector in place of the
parking brake; unexpected and possible sudden vehicle
movement may occur if these precautions are not taken. Always set
the parking brake fully AND make sure the gearshift selector is in R
(Reverse) for vehicles equipped with manual transmission, N (Neutral)
for vehicles with automatic transmission (except Allison 2200
transmission) or P (Park) (Allison 2200 transmission).
If the service brakes should fail to operate while the vehicle is in motion,
you can make an emergency stop with the parking brake. Since the
parking brake only applies stopping power to the rear wheels, the
vehicle’s stopping distance greatly increases and the handling of the
vehicle is adversely affected. Repairs should be made immediately to an
inoperative air brake system circuit.

Parking brake control (knob)
Pull the yellow parking brake knob
out to apply the parking brake. Push
the knob in to release the parking
brake.
WARNING:This control is used for parking only. Do not leave
the vehicle unattended after setting the parking brake without
placing the transmission in R (Reverse) for manual transmission, N
(Neutral) for automatic transmission (except Allison 2200
transmission) or P (Park) (Allison 2200 transmission). Use of wheel
chocks is also recommended in hilly or off-road usage.
The
light illuminates and
remains illuminated (when the
ignition is turned to the on position)
until the parking brake is released.
Releasing spring brake with air pressure
The air system in all vehicles with spring-actuated rear wheel parking
brakes is equipped with a tank valve located on the supply or service air
tank for connection to an outside air supply. The valve permits the
system to be recharged with air from an outside source, releasing the
spring-actuated parking brakes. The vehicle may then be towed in an
emergency.
An outside air source can be used only if the protected system is in
operating condition. If air pressure cannot be restored in the protected
air system, the spring-actuated brakes must be released manually.

EXHAUST BRAKE (IF EQUIPPED)
An exhaust brake is an auxiliary braking system that assists, but does
not replace, the primary service brake system. It is intended to help
control vehicle speed; it is not a vehicle stopping device.
A switch on the instrument panel, in
combination with the accelerator
and clutch pedal, allows the
operator to make maximum use of
the exhaust brake in the following
conditions:
•off-highway driving
•mountain driving
•heavy traffic
•high speed highway driving
To operate the brake, push the switch up to turn it on. Push the switch
down to turn it off.
Note:Before starting the engine, make sure that the exhaust brake
switch is pushed down to the off position. Do not turn the exhaust brake
on until the engine has reached normal operating temperature.
While approaching a steep grade, make sure that the exhaust brake
switch is in the on position. The exhaust brake actuates as soon as you
remove your foot from the accelerator pedal.
Before descending a hill or steep grade always select the proper gear. If
the transmission is taken out of gear while descending, it is possible that
you can’t select another gear because of maximum RPM being governed.
Make sure the engine speed does not exceed the maximum allowable
engine RPM; exceeding the maximum allowable engine RPM can result in
damage to the engine. Apply the service brakes to reduce the engine
RPM or make a slower descent by using a lower gear.
While going down the grade, use a low enough gear to descend safely
with a minimum application of the service brakes. As a general guideline,
use the same gear as you use to ascend the hill.
Note:Engine speed has a major influence of retarding performance.
When engine speed is maintained at the maximum allowable level, the
exhaust brake operates at peak performance.
Note:Maximum exhaust brake performance is related to the type of
transmission your vehicle is equipped with.

Note:Manual transmissions should be downshifted to the lowest gear
possible, without exceeding the maximum RPM limit of the engine. This
maximizes the exhaust brake’s retarding effect.
Note:Exhaust brakes operate effectively with automatic transmissions,
but performance varies with engine speed and the gear selected by the
transmission.
Note:Installing an exhaust or auxiliary brake does not necessarily
protect the engine from exceeding maximum governed speed. The
primary brakes should be used to make sure the engine never exceeds
maximum governed speed under any conditions.
WARNING:The exhaust brake is not recommended for use on
slippery or low traction road surfaces. Under these conditions a
loss of vehicle control could occur.
Exhaust brake operating characteristics
When you remove your feet from both the accelerator and clutch pedals
and the exhaust brake switch is in the on position, the exhaust brake is
activated. The following conditions should exist if the brake is operating
properly:
•A slight change in the sound of the engine when the exhaust brake is
activated.
•A smooth braking effect; do not expect a retarding effect similar to
sudden, hard application of the service brakes.
•The retarding force possibly felt acting against your body when the
brake is applied, depending on the grade and vehicle load. The brake’s
retarding force is actually preventing the vehicle from going much
faster.
•Engine temperature remains in the normal operating range.
•During a descent, the tachometer usually shows a drop in engine RPM
depending on the grade and the vehicle load.
•Road speed usually decreases when the exhaust brake is applied
during a descent, except when the vehicle is carrying a heavy load or
the grade is extremely steep. In these instances, you may need to
apply the service brakes occasionally.

BRAKE-SHIFT INTERLOCK
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents the gearshift lever from being moved from P (Park)
when the ignition is in the on position and the brake pedal is not pressed.
If you cannot move the gearshift lever out of P (Park) with the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or the vehicle’s brake lamps are not operating properly. Refer
toFuses and relaysin theRoadside Emergencieschapter.
If the fuse is not blown and the brake lamps are working properly, the
following procedure will allow you to move the gearshift lever from P (Park):
1. Apply the parking brake, and turn
the engine off.
2. Remove the lower finish panel
below the steering column
3. Turn the key to on (position 4),
but do not start engine.
4. Pull back on the solenoid, and at
the same time, shift the
transmission into N (Neutral).
5. Start the vehicle.
See your authorized dealer as
soon as possible if this
procedure is used.
WARNING:Do not drive
your vehicle until you verify
that the brake lamps are working.

WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel 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. See your authorized dealer.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Main transmission, auxiliary transmission, transfer case and power take-off
(PTO) control shift patterns can be found on a placard or decal on the
driver’s sun visor, on the instrument panel or on the shift control itself.
The main transmission control is used to select the various gear ratios or
speeds of the transmission. Selecting D (Direct Drive), does not change
the transmission gear ratio, but is used where the gear ratios in the main
transmission are adequate to handle the vehicle operation.
If the transmission fails to shift properly, check the inline 10A fuse
located in the battery cables above the battery.
WARNING:Hold the brake pedal down while you move the
gearshift lever between positions. If you don’t hold the brake
pedal down, your vehicle may move unexpectedly and cause property
damage, personal injury or death.
6–speed TorqShifttransmission
This vehicle is equipped with an adaptive transmission shift strategy.
Adaptive transmission shift strategy offers the optimal transmission
operation and shift quality. When the vehicle’s battery has been
disconnected for any type of service or repair, the transmission will need
to relearn the normal shift strategy parameters, much like having to reset
your radio stations when your vehicle battery has been disconnected.
The adaptive transmission shift strategy allows the transmission to
relearn these operating parameters. This learning process could take
