2004 FORD MUSTANG transmission fluid

BRAKE FLUID RESERVOIR
The fluid level will drop
slowly as the brakes
wear, and will rise
when the brake
components are
replaced. Fluid levels below the“MAX”line that do
not trigger the brake system warning lamp are
within the normal operating range, there is no need
to add fluid. If the fluid levels are outside of the
normal operating range, the performance of your
brake system could be compromised, seek service
from your dealer immediately.
CLUTCH ADJUSTMENT (IF EQUIPPED)
Check the clutch
adjustment. Refer to
the scheduled
maintenance guide for
the service interval
schedules.
The clutch on your
vehicle is operated by a
cable. As necessary, adjust the clutch as described
below.
1. Turn the engine off and shift into 1 (First).
2. Put your foot under the clutch pedal and gently
pull it up until the pedal stops.
3. Push the clutch pedal down slowly. You will hear a
click as the clutch adjusts itself.
TRANSMISSION FLUID
Checking automatic transmission fluid
(if equipped)
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
been operated for an extended period at high
speeds, in city traffic during hot weather or pulling a
trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and engage the
parking brake.
3. With the parking brake engaged and your foot on
the brake pedal, start the engine and move the
gearshift lever through all of the gear ranges. Allow
sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean,
dry lint free rag. If necessary, refer toIdentifying
components in the engine compartmentin this
chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in
the filler tube.
7. Remove the dipstick and inspect the fluid level.
The fluid should be in the designated area for
normal operating temperature or ambient
temperature.
Low fluid level
Do not drive the
vehicle if the fluid level
is at the bottom of the
dipstick and the ambient temperature is above 10°C
(50°F).
Correct fluid level
The transmission fluid should be checked at normal
operating temperature 66°C-77°C (150°F-170°F) on
a level surface. The normal operating temperature
can be reached after approximately 30 km (20 miles)
of
driving.

You can check the fluid without driving if the
ambient temperature is above 10°C (50°F). However,
if fluid is added at this time, an overfill condition
could result when the vehicle reaches normal
operating temperature.
The transmission fluid
should be in this range
if at normal operating
temperature (66°C-77°C [150°F-170°F]).
The transmission fluid
should be in this range
if at ambient
temperature (10°C-35°C [50°F-95°F]).
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 also in theLubricant
specificationssection in this chapter.
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.

An overfill condition of transmission fluid may
cause shift and/or engagement concerns and/or
possible damage.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The use of
these materials may affect transmission operation
and result in damage to internal transmission
components.
Checking and adding manual transmission fluid
(if equipped)
1. Clean the filler plug.
2. Remove the filler
plug and inspect the
fluid level.
3. Note: There are two different manual
transmissions used in this vehicle and they have
different fluid levels. For vehicles equipped with a
V6 engine and Cobra the correct manual
transmission fill level is at the lower edge of the
filler hole. For vehicles equipped with a V8 engine
(except Cobra) the correct manual transmission fill
level is 1.3 cm (1/2 inch) below the edge of the filler
hole.

1Add the coolant type originally equipped in your
vehicle.
2Rear axle lubricants do not need to be checked or
changed unless a leak is suspected, service is
required or the axle assembly has been submerged
in water. The axle lubricant should be changed any
time the rear axle has been submerged in water. Fill
6 mm to 14 mm (1/4 inch to 9/16 inch) below
bottom of fill hole. Add 118 ml (4 oz.) of Additive
Friction Modifier XL-3 or equivalent meeting Ford
specification EST-M2C118–A for complete refill of
Traction-Lok axles.
3Ensure the correct automatic transmission fluid is
used. Transmission fluid requirements are indicated
on the dipstick or on the dipstick handle. MERCON
and MERCONV are not interchangeable. DO NOT
mix MERCONand MERCONV. Refer to your
scheduled maintenance guide to determine the
correct service interval.

4Indicates only approximate dry-fill capacity. Some
applications may vary based on cooler size and if
equipped with an in-tank cooler. The amount of
transmission fluid and fluid level should be set by
the indication on the dipstick’s normal operating
range.
5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.
6Use of synthetic or synthetic blend motor oil is not
mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C153–H
and the API Certification mark.
