is not used in the A-904-G and A-904-LA transmis-
sions. Also, it is not used in maximum performance
vehicles with the A-727-A and
B
transmissions.
Inspect the piston and guide seal rings for wear,
and make sure they turn freely in the grooves. It
is
not necessary to remove the seal rings unless condi-
tions
warrant. Inspect the piston for nicks, burrs,
scores and wear. Inspect the piston bore in the case
for scores or other damage. Inspect the
fit
of the
guide on the piston rod. Inspect the piston spring for
distortion.
Inspect the band lining for wear and bond of lin-
ing to the band. Inspect the lining for black burn
marks, glazing, non-uniform wear pattern and flak-
ing. If the lining is worn so the grooves are not visi-
ble at the ends or any portion of the bands, replace
the band. Inspect the band for distortion or cracked
ends.

Inspection
Inspect the seal for deterioration, wear and hard-
ness. Inspect the piston and piston plug
for
nicks,
burrs, scores and wear; piston plug must operate free-
ly in the piston. Inspect the piston bore in the
case
for scores
or
other damage. Inspect the springs for
distortion.
Inspect the band lining for wear and bond of lining
to the band. I f the lining is worn
so
the grooves are
not visible at the ends or any portion of the band,
replace the band. Inspect the band for distortion
or
cracked ends.

ASSEMBLY-SUB-ASSEMBLY
INSTALLATION
The assembly procedures given here include the
installation of the sub-assemblies in the transmission
case and adjusting the drive train end play. Do not
use force to assemble mating parts. I f the parts do
not assemble freely, investigate the cause, and cor-
rect the trouble before proceeding with the assembly
procedures. Always use new gaskets during the as-
sembly operations.
IMPORTANT: Use only Automatic Transmission
Fluid Type "'A"" Suffix "'A'" to lubricate the trans-
mission parts during assembly.
Overrunning Clutch
(1)
Insert the clutch hub (race) inside the overrun-
ning clutch cam, then install the springs and rollers
exactly as shown in Figure 112.
