摘要： In an automatic transmission, friction elements are engaged and disengaged by a hydraulic servo connected alternately to a pressure source or to a drain through a selector valve, and an accumulator is connected to the line between the selector valve and the servo. The resistance against the oil discharged from the accumulator, the resistance against the oil discharged from the servo, and the return biasing forces in the accumulator and servo are adjusted so that the hydraulic pressure at the servo is lower than the hydraulic pressure of the accumulator for a predetermined time when the selector valve connects the servo with the drain. In one embodiment, a relief valve responsive to a vehicle running condition, controls the discharge rate of working oil through the drain. In another embodiment, a pressure regulator varies the level of the pressure of the working oil discharged from the accumulator in response to variations in a vehicle running condition.

摘要： A cut-back pressure control device for a multi-speed automatic transmission includes a cut-back valve that has a spool which is controlled by both hydraulic pressure which changes in response to shifting of a sub-transmission unit between high-speed and low-speed modes and a hydraulic pressure which is established by the operation of the main transmission unit at 2nd or higher speeds. The spool is moved to a position where it interrupts the cut-back pressure when the main transmission unit selects the 1st speed while the sub-transmission unit is in the low-speed mode, whereas, when the sub-transmission unit is in the high-speed mode or when the main transmission unit selects the 2nd or a higher speed, the spool is held at a position at which it permits the supply of the cut-back pressure.

摘要： A rotational speed detecting device for detecting the rotational speed of a predetermined element of a shifting unit is provided for at least one of a main shifting unit and a sub-shifting unit. A control is provided for controlling a predetermined friction engaging element of at least one of the shifting units according to signals from the rotational speed detecting device, so that shifting operations of both the shifting units will be synchronized when both the units are shifted. Therefore, the output of speed of the transmission is not temporarily increased or decreased and thus, smooth shifting is obtained.

摘要： A lock-up clutch control device for an automatic transmission having a torque converter with a lock-up clutch and a speed changing gear mechanism including a sub-transmission unit and a main transmission unit. The device has a lock-up operation device for producing a control signal when the sub-transmission unit is in the higher speed mode or when the main transmission unit selects 2nd or a higher speed gear. The control signal is delivered to a lock-up relay valve which operates effectively while it receives the control signal. Therefore, the torque converter can be locked up at 2nd or higher speeds of the automatic transmission which, because of various combinations of the states of the sub-transmission and main transmission units, outputs multiple speed.
