To determine proper fluid level, proceed as follows:
CAUTION: The full mark on the dipstick is an
indication of transmission fluid at normal oper-
ating temperature of 180°F: This temperature is
only obtained after at least 15 miles of high way
driving or equivalent of city driving.
1. With manual control lever in Park position, start
engine. DO NOT RACE ENGINE. Move manual
control lever through each range.
2. Immediately check fluid level with selector lever in
Park, engine running and vehicle on LEVEL surface.
At this point, when a reading is made, fluid level on the
dipstick should be at the FULL mark.
3. If additional fluid is required, add enough fluid to
bring level to the FULL mark on the dipstick.
If vehicle is not driven 15 expressway miles, or its equiva-
lent, and it becomes necessary to check fluid level, the
transmission fluid must be at room temperature (70°F).
With fluid at room temperature (70"F), follow steps 1, 2
and 3 below:
1. With manual control lever in Park position, start
engine. DO NOT RACE ENGINE. Move manual
control lever through each range.
2. Immediately check fluid level with selector lever in
Park, engine running and vehicle on LEVEL surface.
At this point, when a reading is made, fluid level on the
dipstick should be 1/4" below the ADD mark.
NOTE: I f transmission fluid level is correctly
established at 70°F; it will appear at the FULL
mark on the dipstick when the transmission
reaches normal operating temperature (1 80°F).
3. If additional fluid is required, add fluid to bring level
to 1/4" below the ADD mark on the dipstick.
CAUTION: Do Not Overfill, as foaming and loss
of fluid through the vent pipe might occur as
fluid heats up. If fluid is too low, expecially
when cold, complete loss of drive may result
which can cause transmission Mure.
