Automatic Transmission Fluid Level
A t regular intervals and prior to a long
I
trip, check autom atic transm ission
70
Coolants Lubricants etc.
Check transm ission fluid level with
the engine idling, parking brake
engaged and selector lever in posi­
tion " 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 with the dipstick
com pletely inserted and the locking
lever released (1).
Extreme cleanliness must be
observed! To wipe the dipstick, use a
clean, lintfree cloth. To fill the
transm ission with fluid, 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.
The maximum and minimum fluid level
marks on the d ipstick are applicable
references only if the transmission
fluid has reached its normal operating
tem perature of 80° C/176° F.
If the transm ission fluid cools down to
20 - 30° C /6 8 - 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 (Federal
version) o r 12 mm /0.5 in (California
version) below the minimum mark on
the dipstick. We stress this point
because a fluid change is normally
perform ed when the transmission
fluid has cooled down to shop tem ­
perature.
The fluid level m ust not exceed the
dipstick maximum mark with the fluid
at operating tem perature. Drain or
siphon o ff excess fluid, if required.
Then push dipstick all the way in and
swing locking lever downwards (2).
