Checking
Transmission Fluid Level
Dipstick locking lever
1 Release
2 Engage
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 engine to idle for
approx. 1 to 2 minutes. Measure
fluid level with the dipstick com-
pletely inserted and the locking
lever released
Extreme cleanliness must be ob-
served! To wipe the dipstick, use a
clean, lint-free 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 troubles.
The fluid level in the transmission
is dependent upon its temperature.
The maximum and minimum fluid
level marks on the dipstick are
applicable references only if the
transmission fluid has reached its
normal operating temperature of
176°F (80°C).
Important!
If the transmission fluid cools
down to 68 86°F (20
which is the normal shop tem-
perature range, then the maximum
fluid level will be approximately
0.5 in (12 mm) below the mini-
mum 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).
