(23). Connect the internal wire connector (21) to the
solenoid. Insure that the claw side of the retaining
plate (23) is facing down toward the valve body
surface.

53 lb-in (6 Nm).
3. Install the protective cover gasket (20 onto the valve
body. Position the protective cover (19) over the
gasket. Install lockwashers (18) and capscrews (17),
and tighten until the cover plate is compressed and it
sits flush over the gasket. Torque to 84 lb-in
(9,5 Nm).
4. Install the upper transmission valve body gasket and
upper valve body assembly to transmission.
5. Install the lockwashers and capscrews, and torque
