7. Re-check fluid level at fluid temperatures of approximately 65°C
(149°F) using “HOT” range on A/T fluid level gauge.
CAUTION:
When wiping away the fluid level gauge, always use lint-
free paper, not a cloth one.
To check fluid level, insert the ATF level gauge until the
cap contacts the end of the charging pipe, with the gauge
reversed from the normal attachment conditions as
shown.
8. Check fluid condition.
If fluid is very dark or smells burned, refer to check operation
of A/T. Flush cooling system after repair of A/T.
If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-10,
"RADIATOR" and AT-15, "A/T Fluid Cooler Cleaning" .
9. Install the removed ATF level gauge into the fluid charging pipe.

1. Increase ATF temperature by 80°C (176°F) once.
2. Stop the engine.
3. Remove the tightening bolt for the ATF level gauge.
4. Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained fluid.
To replace the ATF, pour in new fluid at the charging pipe with the engine idling and at the same time
drain the old fluid from the radiator cooler hose return side.
When the color of the fluid coming out is about the same as the color of the new fluid, the replacement
is complete. The amount of new transmission fluid to use should be 30 to 50% increase of the stipu-
lated amount.
CAUTION:
Use only specified ATF fluid. Do not mix with other fluid.
Using ATF other than the specified ATF fluid will cause deterioration in driveability and auto-
matic transmission durability, and may damage the automatic transmission, which is not cov-
ered by the warranty.
When filling ATF, take care not to splash any heat generating parts such as the exhaust.
5. Increase ATF temperature by 80°C (176°F) once.
6. Check fluid level and condition. Refer to MA-21, "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2.
