MAJOR REPAIR OPERATIONS
Before removing any of the sub-
assemblies, thoroughly clean the
outside 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 procedures.
During the transmission dis-
assembly or assembly operations,
ten thrust washers located between
the sub-assemblies must be removed
and installed. It is important that
each thrust washer be in the correct
position during the assembly opera-
tion.
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. Number I
is the first thrust washer located at
the front pump. The last thrust
washer, No. 10, is located at the
parking pawl ring gear.
