A controlled system for the clutch in a torque converter of an automatic transmission wherein the clutch is normally engaged in a predetermined range of vehicle and engine operating conditions for efficient operation. An atmospheric pressure sensor is used in the control system to disengage the clutch in that predetermined range at higher altitudes to allow the torque converter to function to increase the torque being transmitted thereby compensating for the reduced engine performance at higher altitudes. |
