Fluid Level -
Automatic Transmission
At regular intervals and prior to a long
trip, check automatic transmission fluid
level and engine oil level.
Check transmission fluid level with the
engine idling, parking brake engaged
and selector lever in position “ P” . The
vehicle must be parked on level
ground. Prior to the check, allow en­
gine to idle for approx. 1 to 2 minutes.
Measure fluid level with the dipstick
completely inserted and the locking
lever released (1).
Extreme cleanliness must be
observed!
To wipe the dipstick, use a clean,
lintfree cloth.
To fill the transmission with fluid, pour
it through a fine-mesh filter into the
dipstick opening. Even the slightest
impurity may cause operational trou­
bles.
The fluid level in the transmission is
dependent upon its temperature. The
maximum and minimum oil level marks
on the dipstick are applicable refer­
ences only if the transmission fluid has
reached its normal operating tempera­
ture of 80° C/176° F.
If the transmission fluid cools down to
2 0 -3 0 ° C/68-8 6 ° F, which is the nor­
mal shop temperature range, then the
maximum fluid level will be approxi­
mately 12 mm/0.5 in below the
minimum mark on the dipstick. We
stress this point because a fluid
change is normally performed when
the transmission fluid has cooled down
to shop temperature.
The fluid level must not exceed the
dipstick maximum mark with the fluid at
operating temperature. Drain or siphon
off excess fluid, if required.
Then push dipstick all the way in and
swing locking lever downwards (2).
