To reset the speed control to alower speed,
press and hold the COAST switch. Let your
vehicle slow down to the desired speed and
release the COAST switch.
*
[SC09750( ALL)10/94]
Your vehicle has a ªtap-downº feature that
allows you to decrease your current speed in
increments of 1 mph (1.6 km/h) by a
momentary tap of the COAST switch. Multiple
taps of the COAST switch will decrease your
vehicle speed 1 mph (1.6 km/h) for each tap.
For example, if you are currently set at 65 mph
(104 km/h) and tap the COAST switch 5 times
your vehicle speed will decrease and set at
60 mph (96 km/h).

Driving uphill or on a steep grade
*
[SC11200( ALL)05/95]
When the speed control is on, your vehicle may
significantly drop speed when driving uphill,
especially with a heavy load. If the speed drops
more than 8 to 14 mph (15 - 25 km/h) the
automatic speed control will, by design, be
canceled. You may have to temporarily resume
manual speed control while driving up a steep
grade in order to maintain the speed you desire.
*
[SC11250( ALL)03/93]
Frequent shifting of an automatic transmission or
speed loss during speed control operation can be
eliminated by shifting out of overdrive into
drive (or by pressing the Transmission Control
Switch, if equipped). These conditions could
occur in hilly terrain or at higher elevations.
*
[SC11400( ALL)12/91]
If the speed control ªdropped outº after your
climb is completed, the speed of your vehicle
can be reset with the SET ACCEL switch, or
returned to the previous set speed with the
RESUME switch, as long as you are driving over
30 mph (48 km/h).

Your vehicle is equipped with an Electronic
Powertrain Control Module that limits engine
and/or vehicle speeds with a cut-out mode to
promote durability.
*
[DR08650(BEF )03/93]
Automatic Transmission
Operation (E4OD and 4R70W)
*
[DR08710(BEF )03/94]
The E4OD and 4R70W transmissions are
electronically controlled four speed automatic
transmissions 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

176quickly 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.
[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).

[DR08800( ALL)03/94]
Your vehicle's gearshift is on the steering
column. The Transmission Control Switch and
indicator light are located on the end of the
gearshift lever. You can put the gearshift in any
of the several positions.

You will note that there isn't a drive position on
your gearshift indicator. However, you will find
a Transmission Control Switch and an indicator
light labeled ªOverdriveº located on the end of
the gearshift lever. Press this switch and the
word ªOFFº will illuminate on the shift lever
knob. With the word ªOFFº illuminated, the
transmission will operate in gears one through
three. Operating in the Overdrive ªOFFº mode
gives more engine braking than Overdrive and
is useful for descending hills or when towing.

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.
