Automatic Transmission
Operation (E4OD)
[DR08712( M)03/94]
The E4OD transmission is an electronically
controlled four speed automatic transmission
with overdrive. Transmission operation is
controlled by the Powertrain Control Module
(PCM).
*
[DR08720( ALL)08/94]
The PCM will automatically adjust transmission
operation to make up for varying conditions.
Several sensors located on the engine and
transmission such as Throttle Position, Engine
Speed, Vehicle Speed and Transmission
Temperature are used by the PCM to shift the
transmission into a higher or lower gear when
required for the best performance and fuel
economy. For example, you may notice that the
transmission will upshift to a higher gear more
quickly when the vehicle is first driven and has
not reached normal operating temperature.
*
[DR08730( ALL)07/94]
The PCM also controls the transmission's Torque
Converter Clutch to further raise vehicle
performance and fuel economy. The Torque
Converter Clutch will engage when the
transmission operating temperature and other
conditions determined by the PCM have been
met. Engagement of the clutch may be noted as
a decrease in engine speed after an upshift has
completed or when the driver has depressed the
throttle while driving at a steady road speed.

48 [DR08740( ALL)04/95]To help in troubleshooting, the PCM continually
performs self-tests on the electronic control
system and if any faults are detected, will store
them in memory. The Transmission Control
Indicator Light (TCIL), which is located on the
gearshift lever, may flash steadily if a
malfunction has been detected. If the TCIL is
flashing, contact your Ford dealer as soon as
possible. If this condition persists, damage to the
transmission could occur.
[DR08745( ALL)04/95]
NOTE: The word ªOFFº located on the end of
the gearshift lever is the transmission
control indicator light (TCIL).

When to use 2 (Second)
*
[DR10200( ALL)01/95]
Use 2 (Second) to start-up on slippery roads or
to provide additional engine braking on
downgrades. This position provides 2 (Second)
gear operation only.
*
[DR10300( ALL)01/95]
When to use 1 (Low)
*
[DR10400( ALL)04/95]
Use 1 (Low) to provide maximum engine
braking on steep downgrades. Upshifts from 1
(Low) can be made by manually shifting to 2
(Second) orj(Overdrive). Selection of 1 (Low)
gear provides only low gear operation from
start-up. Selection of 1 (Low) while at higher
speeds provides a shift to second gear, and a
shift to first gear will occur after the vehicle
decelerates to the proper speed.
*
[DR10500( ALL)01/95]
P (Park)
*
[DR10600( ALL)03/94]
Always come to a complete stop before you shift
into P (Park). This position locks the
transmission and prevents the rear wheels from
turning. To securely latch the gearshift in the P
(Park) position, pull it toward you, push it
completely counterclockwise against the stop,
and then push it toward the instrument panel.
*
[DR10650( ALL)03/94]

Power Braking
*
[DR11275( ALL)03/94]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.

[DR15915( ALL)01/95]
Steering Your Vehicle
%*
[DR15945( ALL)01/95]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[DR15950( ALL)04/95]
If the amount of effort needed to steer your
vehicle changes at a constant vehicle speed, have
the power steering system checked. If the power
steering system breaks down (or if the engine is
turned off), you can steer the vehicle manually
but it takes more effort.
*
[DR15960( ALL)01/95]
Never hold the steering wheel to the extreme
right or left for more than five seconds if the
engine is running. This can damage the power
steering pump.

Hydraulic Power Brakes
[DR22250( M)06/90]
The hydraulic brake system is made up of two
independent hydraulic circuits. One hydraulic
circuit supplies fluid to the front disc brakes and
the other hydraulic circuit supplies fluid to the
rear disc brakes. These two circuits are supplied
by a common hydraulic brake fluid reservoir,
with a fluid level sensor.

If Brakes Do Not Grip Well or Pedal is
ªLowº
*
[DR23250( ALL)11/89]
If during normal operation the brake pedal
seems ªlowº, it may indicate the need for a
brake system inspection and/or service. You
should have your brakes checked as soon as
possible.
*
[DR23300( ALL)02/95]
Occasional brake squeal during light to moderate
stops does not affect the function of the brake
system and is normal. However, if the squeal
becomes annoyingly loud or increases
significantly in frequency of occurrence, return
the vehicle to your dealer for inspection.

[DR24100( ALL)11/89]
Stopping distances vary with different loads and
driving conditions. Use caution when
encountering new conditions and acquaint
yourself with vehicle performance. Take full
advantage of engine braking power when
slowing down.
%*
[DR24200( ALL)01/95]
Applying the Brakes
*
[DR24300( ALL)05/95]
Apply the brake pedal gradually. Use the
ªsqueezeº technique Ð push on the brake pedal
with a steadily increasing force. This allows the
wheels to continue to roll while you are slowing
down, which lets you steer properly.
*
[DR24400( ALL)05/95]
RWARNING
Do not drive with your foot resting on the
brake pedal. This will increase your
vehicle's stopping distance and may also
cause brake damage.
*
[DR24500( ALL)05/95]
RWARNING
If you are driving down a long or steep
hill, shift to a lower gear. Do not apply
your brakes continuously, as they may
overheat and become less effective.
[DR24550( M)06/90]
When front or rear brake linings are replaced, it
is essential that authorized Ford service
replacement or equivalent linings be installed.
This will assure that the vehicle stopping
distances are not adversely affected and will
maintain the proper balance between front and
rear wheel braking.
