INFORMATION
When you are attempting to define a problem with the
transmission, it is necessary to perform the procedures
that are contained in this section.
If a problem is encountered with the planetary
transmission, recalibrate the transmission prior to
proceeding with investigations.
A visual inspection of the system must be carried out in
order to eliminate many of the less complex problems.
Upon completion of a visual inspection, if the cause of
the problem has not been diagnosed, carry out
operational checks of the system.
If both visual inspection and operational checks have
been carried out and there is still no clear indication of
the cause of the problem. Then it will be necessary to
refer to the troubleshooting procedures and the test
procedures that are contained in the engine service
manual.
Troubleshooting a system such as the transmission is a
complex operation. Refer to the various troubleshooting
sections in this manual for specific routines for
troubleshooting.
This list of possible problems and possible corrections
will only, provide an indication of the location of a
problem and the repairs that are required. It is important
to remember that a problem is not necessarily caused
by a single part, but by the relation of one part to a
number of other parts. This information cannot provide
all the possible problems and corrections. It is
necessary for service personnel to define the problem.
Any repairs may then be carried out.
