A shift device for an automatic transmission of an automobile includes an indicator box affixed to the automobile floor. The indicator box has, in part, a wavy surface and a shift lever which is moved back and forth about an axle by an operator of the automobile. A spring-biased check ball is resiliently held in contact with the wavy surface of the indicator box, and is moved back and forth with respect to the axle in correspondence with motion of the shift lever. The position of the shift lever is regulated by the wavy surface of the indicator box and an indicator is visually provided, so that the shift lever stops accurately at positions of the indicator without needing adjustment during assembly of the selected shift device in a manufacturing assembly line.

Shift device for automatic transmission

In an automatic transmission shift control device, a rocking lever and a second biasing unit are provided for holding a selector lever in a shiftable condition when the selector lever is in one of the gear positions other than a parking position. A first biasing unit is provided for holding the selector lever in a locked condition when the selector lever is in the parking position. A solenoid is provided for releasing the selector lever from a locked condition when energized. The solenoid is energized only when a brake pedal is fully depressed under a condition where an ignition key is in an 'ON' position and the selector lever is in the park position.

Automatic transmission shift control device

Herein disclosed is an improved direction changing mechanism used in a shift control mechanism of a transverse manual transmission. The direction changing mechanism comprises a drive member movable together with the control rod; and at least one driven member movable together with the shift fork. The driven member is formed with a rectangular recess into which a head portion of the drive member is insertable under a certain condition so that upon selecting operation, the head portion of the drive member is put in the recess of the driven member and upon shifting operation, the head portion of the drive member abuts against one of the side walls of the recess thereby to move the driven member in a certain direction thereby completing a gear coupling. The head portion of the drive member is so sized and constructed that when the drive member assumes its rest or neutral position, the head portion is spacedly put in the recess without contacting the driven member, while, when the drive member assumes its operative position to complete the gear coupling, the head portion contact both the side walls of the recess.
