Abstract
A control apparatus for a torque convertor clutch in a transmission including a circuit for engaging the clutch to mechanically interconnect a pump to a turbine of the torque convertor and a mechanism for disabling the circuit when the engine output increases above a predetermined set output value thereby releasing the clutch from engagement. A release preventing mechanism operatively associated with the release mechanism is provided to prevent operation of the release mechanism when the vehicle speed increases above a predetermined set speed value even though the engine output increases above the predetermined set output value.
