Figure 2-6 Transmission O i l Level
The fluid level should be checked at every en-
gine oil change. Add fluid, if necessary, until
proper level is indicated on dipstick, Fig. 2-6.
Proper level is based on operating temperature.
The fluid level should always be checked after the
engine has been running to make certain the fluid
coupling is full. Run the engine with the selector
lever in " N " (Neutral) or " P " (Park) position at
800 RPM for 1-1/2 minutes.
Reduce the engine speed to slow idle, remove
and wipe dipstick, and check fluid level. With the
engine still running, add fluid through the dipstick
tube to bring the fluid to the proper level. At
normal operating temperature, from low mark
(bottom dimple) to " F " requires 1 pint of fluid.
c. Changing Fluid
1. With car on hoist, remove cover plate from
bottom of flywheel housing.
2. Remove drain plugs, Fig. 2-7, from, trans-
mission oil pan and from torus cover.
NOTE: It may be necessary to rotate fly-
wheel to gain access to torus cover drain plug.
Figure 2-7 Transmission Drain Plugs
3. Allow old fluid to drain completely and then
reinstall drain plugs.
4. Pour 7 quarts of Hydra-Matic fluid into the
filler tube.
5. Run engine at a speed of 800 RPM for ap-
proximately 1-1/2 minutes with selector lever in
" P " (Park).
6. Reduce engine speed to slow idle and add
1-1/2 to 2 quarts of fluid to bring level on dip-
stick to proper level as indicated by operating
temperature, Fig. 2-6.
7. Check for leaks at torus cover and drain plug
and replace cover plate on bottom of flywheel
housing and lower car to floor.
8. Turn off ignition and replace dipstick.
NOTE: The capacity of the Hydra-Matic
transmission is approximately 9 quarts for a
refill, but the correct level is determined by the
mark on the dipstick rather than by the amount
added. It is important that the proper level is
maintained. Do not overfill, as foaming may
occur when the fluid heats up. If the oil level is
too low, the pressure regulator will become
noisy, resulting in possible malfunction of the
transmission.
d. Oil Strainer
The oil intake system of the 1963 Hydra-Matic
transmission incorporates an oil strainer in the
transmission oil sump. It is recommended that
the transmission oil strainer be replaced after
the first 30,000 miles only. The procedure for
removing and installing the oil strainer, is des-
cribed in Section 6, Notes 15c and 18f.
8. Front Wheel Bearings
The front wheel bearings on all series cars r e -
quire repacking and adjusting when the front
brakes are serviced, but not before 30,000 miles.
When repacking these bearings, use a #2 grade
high melting point wheel bearing grease free from
any fillers or abrasives. Refer to Section 4 Note
5, for repacking procedure.
9. Battery
The battery electrolyte level should ordinarily
be checked at every engine oil change. In warm
weather, a check should be made at two-week
intervals. If the level is found to be low, add
colorless, odorless drinking water in each of the
six cells to bring the level up to the bottom of the
slot in the well.
