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. Do not
be too hasty in removing the transmission if a fault is suspected, as
most of the testing is carried out with the unit still fitted.
Fluid leakage
MAutomatic transmission fluid is usually dark in colour. Fluid leaks
should not be confused with engine oil, which can easily be blown
onto the transmission by airflow.
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 airflow 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 or “sump” (Chapter 1 and 7B).
b)Dipstick tube (Chapter 1 and 7B).
c)Transmission-to-fluid cooler pipes/unions (Chapter 7B).
Transmission fluid brown, or has burned smell
MTransmission fluid level low, or fluid in need of renewal (Chapter 1).
General gear selection problems
MChapter 7B deals with checking and adjusting the selector cable
on automatic transmissions. The following are common problems
that may be caused by a poorly adjusted cable:a)Engine starting in gears other than Park or Neutral.
b)Indicator panel indicating 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.
MRefer to Chapter 7B for the selector cable adjustment procedure.
Transmission will not downshift (kickdown) with
accelerator pedal fully depressed
MLow transmission fluid level (Chapter 1).
MIncorrect selector cable adjustment (Chapter 7B).
Engine will not start in any gear, or starts in gears
other than Park or Neutral
MIncorrect starter/inhibitor switch adjustment (Chapter 7B).
MIncorrect selector cable adjustment (Chapter 7B).
Transmission slips, shifts roughly, is noisy, or has
no drive in forward or reverse gears
MThere 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.
Clicking or knocking noise on turns (at slow speed
on full-lock)
MLack of constant velocity joint lubricant, possibly due to damaged
gaiter (Chapter 8).
MWorn outer constant velocity joint (Chapter 8).
Vibration when accelerating or decelerating
MWorn inner constant velocity joint (Chapter 8).

* 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.
This should enable the owner can communicate clearly with a
professional mechanic.
