Manual Linkage-Parking Linkage
Inspection
Inspect the parking actuator rod for cracks or broken
spring retainer lugs (fig. 2C-6).
Inspect the actuator rod spring for damage. Inspect
the actuator for a free fit on the actuator rod.
Inspect the parking pawl for cracks or wear and in-
spect the pawl shaft for damaged retainer grooves. In-
spect the pawl return spring for deformed coils"or coil
ends.
Inspect the manual shaft for damaged threads or a
loose lever.
Inspect the inside detent lever for cracks or a loose
pin.
Inspect the parking pawl bracket for cracks or wear.
Inspect the detent roller and spring assembly for
damage.
Transmission Case
Inspection
Inspect the case for cracks, porosity, or interconnected
or restricted oil passages (fig. 2C-117).
Check for good retention of the band anchor pins.
Inspect all threaded holes for thread damage. Inspect
the intermediate clutch driven plate lugs for damage or
signs of wear and inspect the two snap ring grooves for
damage.
Inspect the governor and modulator bores for
scratches or scoring.
Inspect the intermediate clutch cup plug (inside case)
for good staking and sealing (fig. 2C-118).
Inspect the case bushing for wear, scoring, or galling.
Replace the bushing if worn or damaged. Refer to Bush-
ing Replacement in this section.
N O T E : If the case requires replacement, be sure to
remove the center support-to-case spacer from the exist-
ing case and install it in the replacement case. In addi-
ton, if a replacement case is required, be sure to remove
the nameplate from the existing case and transfer it to
the replacement case. Attach the nameplate to the re-
placement case using the truss head-type screws sup-
plied with the service replacement case.
Apply suction to the vacuum tube and check for dia-
phragm leaks.
Check the modulator bellows plunger. The plunger is
under a pressure of 16 pounds. If the bellows are dam-
aged, the plunger will have very little pressure on it.
Inspect the modulator valve for nicks or damage.
However, note that the second spool on the small end of
the valve has a flat spot machined on it. The flat spot
allows a slight bleed and permits some oil to bypass.
This results in a more constant line pressure and pro-
duces smoother shifts.
Check for smooth movement of the valve in the case
bore.
