ABSTRACT:
A system for controlling operation of a bypass clutch for a torque converter in an automatic transmission includes a clutch capacity control valve, which connects a source of fluid pressure to a space between a converter clutch friction surface and an impeller casing in response to a force balance produced by variable pressure control signal and an unlock control pressure signal, produced by a converter lockout valve. The a clutch capacity control valve also supplies pressurized fluid to a torus of the torque converter. The valve includes four control lands connecting 10 ports, all of which are active and independent.
