• Manual lever.
• Manual lever washer, seal, E-clip, and shaft
seal.
• Manual lever detent ball.
• Throttle lever.
• Fluid filter.
• Pressure adjusting screw bracket.
• Governor pressure solenoid.
• Governor pressure sensor (includes transmission
temperature thermistor).
• Converter clutch/overdrive solenoid assembly
and harness .
• Governor housing gasket.
• Solenoid case connector O-rings.

DISASSEMBLY
CAUTION: Do not clamp any valve body component
in a vise. This practice can damage the component
resulting in unsatisfactory operation after assembly
and installation. Do not use pliers to remove any of
the valves, plugs or springs and do not force any of
the components out or into place. The valves and
valve body housings will be damaged if force is
used. Tag or mark the valve body springs for refer-
ence as they are removed. Do not allow them to
become intermixed.
(1) Disconnect wires from governor pressure sen-
sor and solenoid.
(2) Remove screws attaching governor body and
retainer plate to transfer plate.
(3) Remove retainer plate, governor body and gas-
ket from transfer plate.
(4) Remove governor pressure sensor from gover-
nor body.
(5) Remove governor pressure solenoid by pulling
it straight out of bore in governor body. Remove and
discard solenoid O-rings if worn, cut, or torn.
(6) Remove small shoulder bolt that secures sole-
noid harness case connector to 3-4 accumulator hous-
ing (Fig. 286). Retain shoulder bolt. Either tape it to
harness or thread it back into accumulator housing
after connector removal.
(7) Unhook overdrive/converter solenoid harness
from 3-4 accumulator cover plate (Fig. 287).
(8) Turn valve body over and remove screws that
attach overdrive/converter solenoid assembly to valve
body (Fig. 288).
(9) Remove solenoid and harness assembly from
valve body (Fig. 289).
(10) Remove boost valve cover (Fig. 290).
(11) Remove boost valve retainer, valve spring and
boost valve (Fig. 291).
