FLUID LEVEL AT NORMAL OPERATING TEMPERA-
TURE
INSPECTION
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against wheels.
3) With selector at P position, start engine.
4) Warm up engine till fluid temperature reaches normal oper-
ating temperature (70 – 80°C/158 – 176°F). As a guide to
check fluid temperature, warm up engine to normal operat-
ing temperature.
5) Keep engine idling and shift selector slowly to L and back to
P position.
6) With engine idling, pull out dipstick, wipe it off with a clean
cloth and put it back into place.
7) Pull out dipstick (1) again and check fluid level indicated on
it. Fluid level should be between FULL HOT and LOW HOT.
If it is below LOW HOT, add an equivalent of DEXRON
®-III
or DEXRON
®-IIE up to FULL HOT.
A/T fluid specification
: An equivalent of DEXRON
®-III or DEXRON®-IIE
NOTE:
DO NOT RACE ENGINE while checking fluid level, even
after the engine start.
DO NOT OVERFILL. Overfilling can cause foaming and
loss of fluid through breather. Then slippage and
transmission failure can result.
Bringing the level from LOW HOT to FULL HOT
requires 0.35 liters (0.74/0.62 US/Imp. pt).
If vehicle was driven under high load such as pulling a
trailer, fluid level should be checked about half an hour
after it is stopped.
