is at the full mark on the dip stick, it is just slightly be-

low the planetary gear unit. If additional oil is added,

bringing the oil level above the full mark, the planetary

unit will run in the oil, foaming and aerating the oil. This

aerated oil carried through the various oil pressure pas-

sages (low servo, reverse servo, clutch apply, converter,

etc.) may cause malfunction of the transmission assem-

bly, resulting in cavitation noise in the converter and

improper band or clutch application. Overheating may

also occur.

If the transmission is found consistently low on oil, a

thorough inspection should be made to find and correct

all external oil leaks.

PERIODIC OIL CHANGE

The transmission oil should be changed periodically as

recommended in Section 0, and whenever transmission is

to be removed from the vehicle for repairs.

1.
Run engine for one minute in neutral prior to chang-

ing.

2.
Be sure vehicle is level or raise from the rear only.

3.
Remove the oil pan drain plug and allow oil to drain

thoroughly into a pan or can.

Replace drain plug and refill with approximately two

quarts of oil specified in Section 0.

NOTE: To refill the transmission, remove dip

stick from oil filler tube and refill transmission

with oil specified in Section 0 using filler tube

and funnel J-4264. Then, after shifting into all

ranges at idle speed to fill all oil passages, the

engine should be run at 800-1000 rpm with the

transmission in Neutral until the oil warms up,

then add oil as required to raise the fluid level

to the full mark on the dip stick. Refill capacity

is approximately 2 qts.

1PG - Adjusting Low Band Using J-21848
PERIODIC LOW BAND ADJUSTMENT (Fig. 1PG)

Low band adjustment should be periodically performed

at 12,000 mile intervals, or sooner, as necessary if op-

erating performance indicates low band slippage.

1.
Raise vehicle and place selector lever in neutral.

2.
Remove protective cap from transmission adjusting

screw.

3.
a. On Corvette Models: Drop left exhaust pipe for

clearance.

b.
On Chevelle Models: To gain clearance between

underbody and transmission, it may be necessary

to remove rear mount bolts from crossmember,

and move transmission slightly toward passenger

side of vehicle. .

4.
Loosen adjusting screw lock nut 1/4 turn and hold in

this position with wrench.

5.
Using Special Tool J-21848 adjust band to 70 in. lbs.

and back off four (4) complete turns for a band which

has been in operation for 6,000 miles or more,.or

three (3) turns for one in use less than 6,000 miles.

CAUTION: Be sure to hold the adjusting screw

lock nut at 1/4 turn loose with a wrench during"

the.adjusting procedure.

6. Tighten the adjusting screw lock nut to specified

torque.

CAUTION: The amount of back-off is not an

approximate figure, it must be exact.

MANUAL SHIFT LINKAGE CHECK & ADJUST

(Column Type)

1.
The shift tube and lever assembly must be free in the

mast jacket. See Section 9 for alignment of steering

column assembly if necessary.

2.
To check for proper shift linkage adjustment, lift

the transmission selector lever towards the steering

wheel. Allow the selector lever to be positioned in

drive (D) by the transmission detent.

NOTE: Do not use the indicator pointer as a

reference to position the selected lever. When

performing linkage adjustment, pointer is ad-

justed last.

3.
Release the selector lever. The lever should be in-

hibited from engaging low range unless the lever is

lifted.

4.
Lift the selector lever towards the steering wheel,

and allow the lever to be positioned in neutral (N) by

the transmission detent.

5.
Release the selector lever. The lever should now

be inhibited from engaging reverse range unless the

lever is lifted.

6. A properly adjusted linkage will prevent the selector

lever from moving beyond both the neutral detent, and

the drive detent unless the lever is lifted to pass

over the mechanical stop in the steering column.

7.
In the event that an adjustment is required, place

the selector lever in drive (D) position as determined

by the transmission detent. See Steps 2 and 3.

8. Loosen the adjustment swivel at the cross-shaft,

and rotate the transmission lever so that it contacts

the drive stop in the steering column.

9. Tighten the swivel and recheck the adjustment. See

2 and 6.

1.
Raise car on hoist (preferably) or on stand jack and

remove oil pan drain plug to drain oil.

NOTE:
If desired, the oil may be drained after

transmission removal.

2.
Disconnect the oil cooler lines (external cooled

models), vacuum modulator line and the speedometer

drive cable fitting at the transmission. Tie lines

out of the way.

3.
Disconnect manual and TV control lever rods from

transmission.

4.
Disconnect propeller shaft from transmission.

5. Install suitable transmission lift equipment to jack

or other lifting device and attach on transmission.

6. Disconnect engine rear mount on transmission ex-

tension, then disconnect the transmission support

crossmember and slide rearward.

7. Remove converter underpan, scribe flywheel-con-

verter relationship for assembly, then remove the

flywheel-to-converter attaching bolts.

NOTE:
The "light" side of the converter is

denoted by a "blue" stripe painted across the

ends of the converter cover and housing. This

marking should be aligned as closely as possible

with the "white" stripe painted on the. engine

side of the flywheel outer rim (heavy side of

engine) to maintain balance.

8. Support engine at the oil pan rail with a jack or other

suitable brace capable of supporting the engine

weight when the transmission is removed.
9. Lower the rear of the transmission slightly so that

the upper transmission housing-to-engine attaching

bolts can be reached using a universal socket and a

long extension. Remove upper bolts.

CAUTION: Oh V-8 engines, care must be taken

not to lower rear of transmission too far as the

distributor housing may be forced against the

dash causing damage to the distributor. It is

best to have an assistant observe clearance of

all upper engine components while the trans-

mission rear end is being lowered.

10.
Remove remainder of transmission housing-to-

engine attaching bolts.

11.
Remove the transmission by moving it slightly to the

rear and downward, then remove from beneath the

car and transfer to a work bench.

NOTE:
Observe converter when moving the

transmission rearward. If it does not move

with the transmission, pry it free of flywheel

before proceeding.

CAUTION: Keep front of transmission upward

to prevent the converter from falling out. Install

converter Tool J-9549 (or a similar tool con-

structed as shown in Figure 13PG, or, in an

emergency, a length of strong wire may be used)

immediately after removal from the engine.

GENERAL DESCRIPTION

All models
use a 20
gallon capacity (approx.) fuel tank

mounted between
the
frame rails behind
the
rear axle.

The fuel tanks
are
basically
the
same
for
sedan, 2-seat

station wagon
and
pickup models except
for
filler neck

location
and
venting
(fig. 8).

All fuel tanks
are
vented
to the
atmosphere. Sedan

model tanks have
an
external vent hose and pipe assem-

bly
(fig. 11) and use a
non-vented fuel cap. Station wagon

and pickup model tanks
are
vented through
a
hose
and

vent pipe assembly
to the
filler neck
(fig. 8)
and
use a

vented, anti-surge type
gas cap. The
fuel caps
are two

different designs conforming
to SAE
standards
and are

not interchangeable.

The filler neck assembly
on
sedan models
is a
rear

fill design located behind
the
center
bar of the
bumper.
Station wagon
and
sedan pickup model filler neck assem-

blies
are
located
in
the left rear quarter panel.

The fuel pickup pipe
is
built integrally with
the
tank

gauge, located
at the
top-front center
of
the tank.
A
fine

mesh screen
is
located
at
the bottom-end
of the
fuel pick-

up pipe
to
prevent
the
entrance
of
foreign material into

the fuel system.

The sedan fuel tanks
are
held
in
place
by
two metal

straps attached individually
to the
underbody
at
each
end.

The straps hinge
at the
forward end and secure
the
tank

at
the
rear with
an
adjustable bolt
and nut
assembly.

The station wagon
and
pickup models have
a
frame

mounted fuel tank secured with straps
to
front and rear

supports.

carburetor
or
fuel pump
on

the
lines should

be disconnected
and
