h. Lockup Clutch Cutoff Valves (fig. 1-23).
Each of the three
lockup clutch cutoff valves consists of a valve in a bore.
lockup clutch cutoff valves move in their bores in response to
individual clutch pressure.
The valves delay pressure momentarily
and allow pressure to charge the lockup feed lines by exhausting
clutch pressure on one end of a valve and exerting another clutch
pressure through an orifice on the opposite end.
