Speedometer
*
[LG12700(ALL)01/95]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[LG12750(ALL)08/95]
Your vehicle contains a speedometer which
receives its input from the Anti-Lock brake
sensor. The speedometer is also used to provide
a speed signal for correct operation of the
vehicle's Powertrain Control Module (PCM),
electronic transmission, and speed control (if so
equipped). Because of this, it is very
IMPORTANT to change the speedometer's
internal conversion constant if the size of the
tires on the vehicle is changed. Changing the
conversion constant to the proper value when
the tires are changed will also ensure that the
speedometer retains the original factory-set
accuracy.
[LG12752(ALL)08/95]
NOTE: The conversion constant can only be
changed six times once the vehicle
leaves the factory. Your Ford dealership
service personnel can change the
conversion constant.
*
[LG12753(ALL)08/95]
Some vehicles are equipped with a vehicle speed
(mph/km/h) limiting device that is contained
within the Powertrain Control Module (PCM).
The purpose of this device is to maintain peak
vehicle speed below a specified limit. (Vehicle
speed limits may vary based on engine
displacement.)

half page art:0095007-A[SC08630(ALL)07/95]
NOTE: If your speed increases above your set
speed while driving inj(Overdrive)
on a downhill grade, you may want to
select Drive (by cancelling Overdrive)
to reduce vehicle speed. This can be
accomplished by pushing in the
transmission control switch located on
the end of the gearshift lever. The
speed control cannot reduce the vehicle
speed if it goes above your set speed
on a downhill grade. For the best fuel
economy during normal driving
conditions, leave the transmission inj
(Overdrive), or return to Overdrive as
soon as practical.

Do not use the speed control in heavy
traffic or on roads that are winding,
slippery, or unpaved.

[SC08801(ALL)05/95]
In mountainous areas, at higher elevations, or
when pulling a trailer, the speed control may
not be able to maintain the preset speed with
the transmission inj(Overdrive).
[SC08900(ALL)07/95]
To maintain a preset speed with an automatic
transmission under these conditions, select Drive
by cancelling Overdrive. You can switch to
Drive at any speed. For the best fuel economy
duringnormaldriving conditions, leave the
transmission inj(Overdrive).

Automatic Transmission
Operation (4R44E/4R55E)
*
[DR00350(ALL)08/95]
The 4R44E and 4R55E transmissions are
electronically controlled four speed overdrive
automatic transmissions with lockup torque
converter. Transmission operation is controlled
by the Powertrain Control Module (PCM).
*
[DR00425(ALL)08/95]
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 has not reached normal
operating temperature.
*
[DR00475(ALL)08/95]
The PCM also controls the transmission's Torque
Converter Clutch (TCC) to further raise vehicle
performance and fuel economy. The TCC 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.
[DR00500(ALL)08/95]
To help in troubleshooting, the PCM continually
performs self-tests on the electronic control
system and, if any faults are detected, stores
them in memory. The Overdrive Off Indicator
Light (O/D OFF), which is located on the

malfunction has been detected. If the Overdrive
Off Indicator Light is flashing, contact your Ford
dealer as soon as possible. If this condition
persists, damage to the transmission could occur.

Some vehicles are equipped with a Powertrain
Control Module that limits engine speeds with a

This is the normal driving position. As the
vehicle picks up speed, automatic upshifts to
second, third and fourth gears will occur when
jOverdrive is chosen on the selector and the
transmission control switch has not been
pressed. The transmission will shift into the
correct gear when the right speed is achieved,
for the accelerator pedal position you have
chosen.

You will note there is not a drive position on
your gearshift indicator. However, you will find
a transmission control switch labeled
OVERDRIVE OFF located on the end of the
gearshift lever. Press this switch and the
indicator light (OFF) illuminates on the gearshift
lever. With overdrive cancelled and the word
OFF illuminated, the transmission will operate in
gears one through three. This is useful if you
experience frequent downshift/upshift
conditions, when operating with a heavy load or
in hilly terrain, or if additional engine braking is
