TRANSMISSION AT ROOM TEMPERATURE (65°
to 85°F) - Automatic transmissions are frequently
overfilled because the fluid level is checked when the
fluid is cold and the dipstick indicates fluid should be
added. However, the low reading is normal since the
level will rise as the fluid temperature increases. A
level change of over
Y,
inch will occur as fluid
temperature rises from 60° to 180°F.
Overfilling can cause foaming and loss of fluid
through the vent. Slippage, transmission failure or fire
can result.
Fluid level too low can result in transmission charg-
ing pump cavitation, a loss of main and lubrication
oil pressure and clutch plate damage. It can cause
slipping, particularly when the transmission is cold or
the vehicle is on a hill.
Check the transmission fluid level with the engine
running, the shift lever in PARK, and the vehicle level.
If the vehicle has recently been operated for an ex-
tended period at high speed or in city traffic in hot
weather or the vehicle is being used to pull a trailer,
an accurate fluid level cannot be determined until the
fluid has cooled down, usually about 30 minutes after
the vehcile has been parked.
Remove the dipstick and touch the transmission end
or the dipstick cautiously to find out if the fluid is cool,
warm or hot.
Wipe the dipstick clean and reinsert it until the cap
seats. Remove the dipstick and note reading.
,l.lf the fluid feels cool, about room temperature,
(65° to 85°F), the level should be between the
two dimples below the" ADD" mark.
2. If it feels warm the level should be close to the
"ADD" mark (either above or below).
3. If it feels hot (cannot be held comfortably). the
level should be between the "ADD" and
"FULL" marks.
Changing Fluid
1. Raise the vehicle.
2. Whh a drain pan placed under
~he
transmission
oil pan, remove the oil pan attaching bolts from
the front and side of the pan.

7. If required, remove the

body bolts. Remove screen/filter and gasket.
8. Thoroughly clean screen assembly in solvent
and dry thoroughly with clean compressed air.
Paper or felt-type filters should be replaced.
9. Install, as required, a new gasket or "0" ring
onto the screen filter assembly. Lubricate "0"
rings with petrolatum. If required, install the
screen/filter attaching bolts and torque.
10. Install a new gasket on the oil pan and install
the pan. Torque the attaching bolts to 12 ft. Ibs.
11. Lower the vehicle and add the proper amount
of DEXRON-II automatic transmission fluid or
its equivalent through the filler tube.
12. With the selector lever in PARK position, app-
ly the parking brake, start the engine and let
idle (carburetor off fast idl,e step). DO NOT
RACE ENGINE.
13. Move the selector lever through each range
and, with the selector lever in PARK range,
check fluid level.
14. Add additional fluid to bring the level between
the dimples on the dipstick (cool levell.
HEA TING AND AIR CONDITIONING
The heater system consists of a heater core housed
in a case which, typically, includes an air inlet, blower
motor assembly, air distribution ducts and doors to
control the flow of air through the case.
Troubleshooting the System
Problems of·toolittle or no heat, 'poor, air circula-
tion, or inadequate defrosting action are sometimes
encountered with a heater system.
