Transmission at Room Temperature
(80°F)-If the vehicle has not been
driv~n
sufficiently to bring the trans-
mission up to operating temperature,
the fluid level should be checked as
follows:
1. Apply the parking brake, put the
selector lever in PARK, and start
the engine. Note: Do Not Race the
Engine. Move the selector lever
through each range.
2. Immediately check the fluid level
with the selector lever in the
PARK position. The engine should
be running at a slow idle and the
vehicle should be level. The fluid
level on the dipstick should be
between the "ADD" mark and %
inch below.
3. If additional fluid is required, add
sufficient fluid to bring the level to
1/4
inch below the "ADD" mark on
the dipstick.
If the transmission fluid level can
be correctly established at room tem-
perature (80°F) as described, when
the transmission reaches normal op-
erating temperature, the fluid level
will appear at the "FULL" mark. The
fluid level is set at
lJ4
inch below the
"ADD" mark on the dipstick to allow
for expansion of the fluid which oc-
curs as the transmission temperature
rises to its normal operating point of
180°F. DO NOT OVERFILL.
