ABSTRACT:
A control system for an automatic vehicle transmission includes a clutch mechanism interconnecting the driving connection between the vehicle engine and the vehicle driving wheels. The control system operates to automatically disengage the clutch when the braking system is actuated and the vehicle speed is reduced to a predetermined level with the accelerator in idle position. The clutch automatically engages when any of the three parameters have changed from predetermined levels. The automatic control system serves to reduce fuel consumption and exhaust emissions at vehicle idling by reducing transmission drag, yet provides smooth shifting and permits the engine and transmission to assist in vehicle braking.
