The transmission consists essentially

of a torque converter, planetary gear

train, two multiple disc clutches, a
one-way clutch and a hydraulic con-

trol system (Fig. 3).

The only adjustments on the trans-
mission proper are the intermediate

and low-reverse bands.

LINKAGE ADJUSTMENTS

Adjusting the throttle linkage is im-

portant to be certain the throttle and

kickdown systems are properly adjust-

ed. The kickdown system should come

in when the accelerator is pressed

through detent, and not before detent.

Refer to Group 10 for detailed

throttle and downshift linkage adjust-

ment procedures.

MAJOR REPAIR OPERATIONS

Before removing
any of the sub-

assemblies, thoroughly clean
the out-

side
of the
transmission
to
prevent dirt

from entering
the
mechanical parts.

During
the
repair operations, refer
to

Part 7-1
for
common adjustments
and

repairs
or
cleaning
and
inspection
pro-

cedures.

During
the
transmission disassem-

bly
or
assembly operations,
ten
thrust

washers located between
the sub-

assemblies must
be
removed
and in-

stalled.
It is
important that each

thrust washer
be in the
correct posi-

tion during
the
assembly operation.

To properly locate
and
identify
the

thrust washers,
the
various positions

of
the
thrust washers
are
shown
in the

illustrations
and are
numbered
1

through
10. No. 1 is at the
first thrust

washer located
at the
front pump.
The

last thrust washer,
No. 10, is
located

at
the
parking pawl ring gear.
