1985 FORD GRANADA suspension

The vehicle owner who does his or her own maintenance according
to the recommended service schedules should not have to use this
section of the manual very often. Modern component reliability is such
that, provided those items subject to wear or deterioration are
inspected or renewed at the specified intervals, sudden failure is
comparatively rare. Faults do not usually just happen as a result of
sudden failure, but develop over a period of time. Major mechanical
failures in particular are usually preceded by characteristic symptoms
over hundreds or even thousands of miles. Those components which
do occasionally fail without warning are often small and easily carried
in the vehicle.With any fault-finding, the first step is to decide where to begin
investigations. Sometimes this is obvious, but on other occasions, a
little detective work will be necessary. The owner who makes half a
dozen haphazard adjustments or replacements may be successful in
curing a fault (or its symptoms), but will be none the wiser if the fault
recurs, and ultimately may have spent more time and money than was
necessary. A calm and logical approach will be found to be more
satisfactory in the long run. Always take into account any warning
signs or abnormalities that may have been noticed in the period
preceding the fault - power loss, high or low gauge readings, unusual
smells, etc - and remember that failure of components such as fuses or

*Although the corrective action necessary to remedy the symptoms
described is beyond the scope of the home mechanic, the above
information should be helpful in isolating the cause of the condition, so
that the owner can communicate clearly with a professional mechanic.
6Automatic transmission
Note:Due to the complexity of the automatic transmission, it is difficult
for the home mechanic to properly diagnose and service this unit. For
problems other than the following, the vehicle should be taken to a
dealer service department or automatic transmission specialist.
Fluid leakage
m m
Automatic transmission fluid is usually deep red in colour. Fluid
leaks should not be confused with engine oil, which can easily be
blown onto the transmission by air flow.
m mTo determine the source of a leak, first remove all built-up dirt and
grime from the transmission housing and surrounding areas, using a
degreasing agent or by steam-cleaning. Drive the vehicle at low speed,
so that air flow will not blow the leak far from its source. Raise and
support the vehicle, and determine where the leak is coming from. The
following are common areas of leakage:
a)Fluid pan ( transmission “sump”).
b)Dipstick tube (Chapter 1).
c)Transmission-to-fluid cooler fluid pipes/unions (Chapter 7B).
3Fuel and exhaust systems
procarmanuals.com

Transmission fluid brown, or has burned smell
m m
Transmission fluid level low, or fluid in need of renewal (Chapter 1).
General gear selection problems
m m
The most likely cause of gear selection problems is a faulty or
poorly-adjusted gear selector mechanism. The following are common
problems associated with a faulty selector mechanism:
a)Engine starting in gears other than Park or Neutral.
b)Indicator on gear selector lever pointing to a gear other than
the one actually being used.
c)Vehicle moves when in Park or Neutral.
d)Poor gear shift quality, or erratic gear changes.
m
mRefer any problems to a Ford dealer, or an automatic transmission
specialist.
Transmission will not downshift (kickdown) with
accelerator pedal fully depressed
m m
Low transmission fluid level (Chapter 1).
m
mIncorrect selector adjustment (Chapter 7B).
Engine will not start in any gear, or starts in gears
other than Park or Neutral
m m
Faulty starter inhibitor switch (Chapter 7B).
m
mIncorrect selector adjustment (Chapter 7B).
Transmission slips, shifts roughly, is noisy, or has no
drive in forward or reverse gears
m m
There are many probable causes for the above problems, but the
home mechanic should be concerned with only one possibility - fluid
level. Before taking the vehicle to a dealer or transmission specialist,
check the fluid level and condition of the fluid as described in Chapter 1.
Correct the fluid level as necessary, or change the fluid and filter if
needed. If the problem persists, professional help will be necessary.

movement is transmitted through the track
rods to the steering arms at the wheels.

designed to reduce the temperature of the
coolant in an internal combustion engine
cooling system.

transfer agent in an air-conditioning system.
