automatic transmission fluid FORD MUSTANG 1999 4.G Owners Manual

To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme
right or the extreme left for more than a few
seconds when the engine is running.
²Do not operate the vehicle with a low power
steering pump fluid level.
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.
If the steering wanders or pulls, the condition could
be caused by any of the following:
²underinflated tire(s) on any wheel(s)
²high crown in center of road
²high crosswinds
²wheels out of alignment
²loose or worn components in steering linkage
AUTOMATIC TRANSMISSION OPERATION
(IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock
feature that prevents the gearshift from being moved
from P (Park) unless the brake pedal is depressed.
If you cannot move the gearshift out of P (Park)
with the brake pedal depressed:
1. Apply the parking brake, turn ignition key to
LOCK, then remove the key.
2. Insert the key and turn it to OFF. Apply the brake
pedal and shift to N (Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to
move the gearshift, it is possible that a fuse has
blown or the vehicle's brakelamps are not operating
properly. Refer toFuses and relaysin theRoadside
emergencieschapter.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine
compartment for easy location.
²We provide a Scheduled Maintenance Guide which
makes tracking routine service easy.
If your vehicle requires professional service, your
dealership can provide necessary parts and service.
Check your ªWarranty Guideº to find out which parts
and services are covered.
Use only recommended fuels, lubricants, fluids and
service parts conforming to specifications. Motorcraft
parts are designed and built to provide the best
performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR
VEHICLE
Be especially careful when inspecting or servicing
your vehicle.
²Do not work on a hot engine.
²When the engine is running, keep loose clothing,
jewelry or long hair away from moving parts.
²Do not work on a vehicle with the engine running
in an enclosed space, unless you are sure you
have enough ventilation.
²Keep all lit cigarettes, open flames and other lit
material away from the battery and all fuel related
parts.
If you disconnect the battery, the engine must
ªrelearnº its idle conditions before your vehicle will
drive properly, as explained in theBatterysection in
this chapter.
Working with the engine off
²Automatic transmission:
1. Set the parking brake and ensure the gearshift is
securely latched in P (Park).

Maintenance and care

If your vehicle is
equipped with a 4.6L
V8 engine,check the
power steering fluid
level with the engine at
ambient temperature.
Allow at least one-half
hour after driving for
the power steering
fluid to cool.
1. Start the engine and
allow the engine to
idle.
2. Turn the steering
wheel left and right
several times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be
between the MIN and MAX lines. Do not add fluid if
the level is within this range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
correct operating range. Be sure to put the cap back
on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your Scheduled Maintenance Guide for
scheduled intervals for fluid checks and changes.
Your transmission does not consume fluid. However,
the fluid level should be checked if the transmission
is not working properly, i.e., if the transmission slips
or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed.
To obtain an accurate fluid check, drive the vehicle
until it is at normal operating temperature
(approximately 30 km [20 miles]). If your vehicle has
MAXMIN
Maintenance and care

could result when the vehicle reaches normal
operating temperature.
The transmission fluid
should be in this range
if at normal operating
temperature (66ÉC-77ÉC [150ÉF-170ÉF]).
The transmission fluid
should be in this range
if at ambient
temperature (10ÉC-35ÉC [50ÉF-95ÉF]).
High fluid level
Fluid levels above the
safe range may result
in transmission failure.
An overfill condition of transmission fluid may cause
shift and/or engagement concerns and/or possible
damage.
High fluid levels can be caused by an overheating
condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type
is used. The type of fluid used is normally indicated
on the dipstick and/or dipstick handle and also in
theLubricant specificationssection in the
Capacities and specificationschapter.
Use of a non-approved automatic transmission
fluid may cause internal transmission
component damage.
If necessary, add fluid in 250 mL (1/2 pint)
increments through the filler tube until the level is
correct.
If an overfill occurs,
excess fluid should be
removed by a qualified
technician.

3Ensure the correct automatic transmission fluid is
used. Transmission fluid requirements are indicated
on the dipstick or on the dipstick handle. MERCONt
and MERCONtV are not interchangeable. DO NOT
mix MERCONtand MERCONtV. Refer to your
Scheduled Maintenance Guide to determine the
correct service interval.
4Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.
