Autom Atic Transmission Fluid Level - Mercedes-Benz 300 D 1984 Owner's Manual

Automatic Transmission Fluid Level
A t regular intervals and prior to a long
trip, check autom atic transm ission
fluid level and engine oil level.
Check transm ission fluid level with
the engine idling, parking brake
engaged and selector lever in posi­
tio n " P" . The vehicle m ust be parked
on level ground. Prior to the check,
allow engine to idle fo r approx. 1 to
2 minutes.
Measure fluid level w ith the dipstick
com pletely inserted and the locking
lever released (1).
Extreme cleanliness m ust be
observed! To wipe the dipstick, use a
clean, lintfree cloth. To fill the
transm ission with fluid, only pour it
through a fine-m esh filte r into the
d ipstick opening. Even the slightest
im purity may cause operational tro u ­
bles.
The fluid level in the transm ission is
dependent upon its tem perature.
Checking Fuels C o o lants
The maximum and minimum fluid level
marks on the dipstick are applicable
references only if the transm ission
fluid has reached its normal operating
tem perature of 80° C /1760 F.
If the transm ission fluid cools down
to 2 0 - 3 0 ° C/68 - 8 6 ° F, which is
the normal shop tem perature range,
then the maximum fluid level will be
approxim ately 5 mm /0.2 in below the
minimum mark on the dipstick. We
stress this point because a fluid
change is normally perform ed when
the transm ission fluid has cooled
down to shop tem perature.
The fluid level m ust not exceed the
d ip stick maximum mark with the fluid
at operating tem perature. Drain or
siphon off excess fluid, if required.
Then push d ipstick all the way in and
swing locking lever downwards (2).
