Troubleshooting - Mitsubishi 3000GT 1991 Service Manual

AUTOMATIC TRANSAXLE
Based upon use of the troubleshooting
Checks should be made of fluid levels and
the condition of the ATF, as well as the
condition of the manual control cables;
adjustments should then be made if found
to be necessary.
If a presumption has been made that there
is an abnormal condition somewhere in
the electronic-control system, check the
fault code, in order to determine the
probable location of the problem, by using
a multi-use tester or voltmeter.
I
When the abnormal system is discovered,
check each element (sensors, etc.) one by
one, and make repairs as necessary.
When the abnormal condition is presumed
to be in the oil-pressure-control system
When the result of the oil-pressure test
does not satisfy the specified pressure,
check each system at places related to the
valve body, check the oil-pressure pas-
sages for leakage, etc.
I
If the problem isunusually dirty ATF,
abnormal noises, oil leakage, or slippage of
the clutch or brakes, or an abnormal
condition of the transaxle itself, disassem-
ble and repair the transaxle.
Functional malfunctions of the ELC4A/T can lead to other
problems, such as those described below:
(3) Malfunctions of mechanical functions
etc.
In order to properly determine ("Troubleshoot") the source of
these malfunctions, it is first essential to methodically question
the user concerning the details of the problem, such as the
condition of the problem, the situation at the time the problem
occurred, and any other relevant information, all in as much
detail as possible. The user should also be asked whether or
not the problem has occurred more than once, and under what
conditions.
Subsequently, certain tests should be conducted in a certain
order, as described at the left.
