Automatic Transmission Fluid Level - Mercedes-Benz 380 SL Owner's Manual

Automatic Transmission Fluid Level

At regular intervals, check the fluid
level of the automatic transmission
together with the engine oil level
prior to every long trip.
Check transmission fluid level with
the engine idling, parking brake
engaged and selector lever in posi­
tion " P". The vehicle must be
parked on level ground. Prior to the
check, allow engine to idle for
1 2
approx. to minutes.
Measure oil level with the dipstick
completely inserted and the locking
1
lever released ( ).
Painstaking cleanliness must be
observed! To wipe the dipstick, use
a clean, lint-free cloth (preferably
leather). To fill the transmission with
fluid, only pour it through a fine-
mesh filter into the dipstick ope­
ning. Even the slightest impurity
may cause operational troubles.
The oil level in the transmission is
dependent upon the oil tempera­
ture. The maximum and minimum
oil level marks on the dipstick are

applicable references only if the
transmission fluid has reached its
normal operating temperature of
80° C /176° F. - If, however, the
transmission fluid cools down to
68 86
2 0 -3 0 ° C / - ° F, which is the
normal shop temperature range,
then the maximum oil level will be
approximately 5 mm/0.2 in below
the minimum mark on the dipstick.
We stress this point because an oil
change is normally performed when
the transmission oil 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 requi­
red.
Then push dipstick all the way
in and swing locking lever down­

wards ( ).
