Abstract: A selection system for an automatic motor vehicle transmission has a selector element for selecting transmission adjustments (P, R, N, D) which can be manually adjusted. A toggle lever arrangement connected with the selector element acts transversely to the moving direction of a locking element. As a result, a manual force on the selector element cannot be transmitted or can only be transmitted in a highly reduced manner to the locking element. To reduce the overall size of the systems, the locking element is preferably an armature of a solenoid arranged parallel to the axes of rotation of the toggle lever arrangement.

Abstract: A shift lock arrangement for an automatic transmission shift lever device having a shift lock lever in contact with a position pin of the shift lever device positioned in a parking position has a lock lever in contact with the shift lock lever to restrict the movement of the position pin in the parking position. A key lock unit is connected with the shift lock lever so that the shift lock lever keeps latching the position pin in the parking position when an automotive key is not set therein. A slidable stopper pin is connected with a push rod pushed by a brake pedal in a released condition. The stopper pin latches the shift lock lever so as to prevent the movement of the position pin from the parking position to the other positions when the brake pedal is in the released condition. When the brake pedal is depressed, the push rod is released from the brake pedal and the stopper pin is disengaged from the shift lock lever.

Abstract: In a selector device for an automatic transmission system, a rotatable member is supported by a first pivot shaft, and a selector lever is tiltably supported by the rotatable member by a second pivot shaft extending substantially perpendicularly to the first pivot shaft. A base end of the selector lever is bifurcated into a pair of engagement claws, and a checker cam is positioned in a gap defined between the engagement claws. A slide member can be slid into between the checker cam and the associated engagement claw to prevent the tilting movement of the selector lever. Thus, the slide member which is typically associated with a shift lock mechanism can prevent the tilting movement of the selector lever and, hence, the shifting of the selector lever from the P range position. Because the force applied to the selector lever is supported by the slide member as a compressive load, no substantial stress is applied to the actuator or the linkage provided between the actuator and the slide member.

Abstract: A hydrostatic transmission control mechanism includes a hand lever engagable by an operator, and a member to which the hand lever is directly mounted.
