extension to the wide open throttle position (defined
by wide open throttle and full cable travel).

MINOR SERVICE AND REPAIR
Services outlined in this section can be performed
without removing the transmission from the car.
Complete procedures are not given for all of these
services, since they are covered in detail under
disassembly, overhaul and reassembly.
FLUID LEVEL
The fluid level indicator is located in the filler tube at
the right rear of the engine. To bring the fluid lever
from the ADD mark to the FULL mark requires one
pint of fluid.
Fluid level should be to the FULL mark with the
transmission fluid at normal operating temperature
(1 80- 1 90°F). With warm fluid (room temperature
-
70"F), the level will be as much as 7/10" below the
ADD mark on the dipstick.
NOTE: In checking the oil, insert the dipstick in the
filler tube with the markings toward center of car.
CHECKING PROCEDURE
To determine the proper fluid level, proceed as
follows:
CAUTION: The FULL mark on the dipstick is an
indication of transmission fluid at its normal operating
temperature of 181PF. This temperature is only obtained
afrer at leas! I5 miles of highway type driving or the
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 idling 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 miles of highway type
driving, or its equivalent, and it becomes necessary to
check the fluid level, the transmission fluid level must
be
at room temperature ( 7 0 ' F ) .
With the 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. Mcve manual
control lever through each range.
2. Immediately check fluid level with selector lever
in
PARK, engine idling and vehicle on LEVEL surface.
At this point, when a reading is made, fluid level on
the dipstick will be as much as 7/ 10" below the ADD
mark on the dipstick.
3. If additional fluid is required, add enough fluid to
bring level to 7/10" below the ADD mark on the
dipstick. If transmission fluid level is correctly estab-
lished at 70°F, it will appear at the FULL mark on the
dipstick when the transmission reaches its normal
operating temperature of 180°F.
CA UTION: Do not overfill , as foaming and loss ,of
fluid through the vent pipe might occur asfluid heats up.
If fluid is too low, especially when cold, complete loss of
drive may result which can result which can cause
transmission failure.
IMPORTANT When adding fluid, use only DEXRON
automatic transmission fluid. The dgerence in oil level
between ADD and FULL is onepint.
FLUID CAPACITY
Approximately 5 pints of fluid are required to refill
transmission after oil pan has been drained. When unit
has been disassembled and rebuilt, approximately 10 pints
will be required to refill. Use only DEXRON automatic
transmission fluid, or equivalent.
DRAINING AND REFILLING TRANSMISSION
Drain oil immediately after operation before it has
had an opportunity to cool.
To drain oil, proceed as [ollows:
1. Raise car on hoist or place on jack stands and place
container beneath transmission to collect draining
fluid.
2. Remove thirteen (13) oil pan attaching bolt and
washer assemblies, oil pan and gasket. Discard gasket.
3. Drain fluid from oil pan. Clean pan with solvent
and dry thoroughly with clean compressed air.
4. Remove two (2) strainer-to-valve body screws,
strainer and gasket. Discard gasket.
5. Thoroughly clean strainer assembly in solvent and
dry
thoroughly
with
clean compressed
air.
