CAUTION:
lWhen wiping away A/T fluid level gauge, always use lint-free paper, not a cloth one.
lTo check A/T fluid level, insert A/T fluid level gauge until
the cap contacts the end of A/T fluid charging pipe, with
A/T fluid level gauge reversed from the normal attach-
ment conditions as shown.
8. Check A/T fluid condition.
lIf ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.
lIf A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer toCO-11,
"RADIATOR".
9. Install the removed A/T fluid level gauge into A/T fluid charging
pipe.
10. Tighten level gauge bolt to the specified torque. Refer toAT-247,
"COMPONENTS".

TROUBLE DIAGNOSIS
How to Perform Trouble Diagnosis for Quick and Accurate Repair
ECS00FWX
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelera-
tor pedal position sensor or PNP switch and provides shift control or
lock-up control via A/T solenoid valves.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose a error that occurs intermittently
rather than continuously. Most intermittent errors are caused by poor
electric connections or improper wiring. In this case, careful check-
ing of suspected circuits may help prevent the replacement of good
parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II or a circuit tester connected should be performed.
Follow theAT-37, "
WORK FLOW".
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSFEET” as
shown on the example (Refer toAT-38
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
