In a selector lever system for manually shiftable automatic transmissions for motor vehicles, comprising a selector lever movable in a gear shifting gate in only one plane in a plurality of gear shift positions. The shift positions include a manual drive position from which the lever can be moved into a first direction to command an upshift and in a second direction to command a downshift. The lever is biased back to the manual drive position after the upshift or downshift command is given. The system also includes sensors for detecting movement in the first and second directions from the manual drive position. The system includes a cam and spring loaded pin which prevents the lever from being positioned in the manual drive position.

Selector lever system for manually shiftable automatic transmissions

A selector lever arrangement for an automatic transmission, comprising a lever (10) in a housing (2) pivotable about a horizontal transverse axle (9), wherein the housing (2) is dome-shaped with side walls (4 to 6) and is covered by a member (14) and a cover (20) with a gate, and wherein lever (10) has a hand grip (11) with a control knob (12), a catch device (19) operated by the control knob (12) by which the lever (10) is pivotably mounted on axle (9), the mounting member (13) being connected to a Bowden cable linkage (27) which transmits movements to the shift input element of the automatic gearbox.

Selector lever arrangement for an automatic transmission of a motor

A steering column shift mechanism having a wheel brake interlock includes a gear selector shaft moved by a gear selector action initiated by the vehicle operator manually by manipulating a gear selector lever between a park position and at least one drive position. A brake pedal actuates a switch within an electrical circuit containing an electrical solenoid and a power supply to actuate a locking bolt that blocks movement of the selector shaft unless the brake pedal is depressed. The selector lever includes an arm extending into a shift gate containing a system of interconnected recesses corresponding to selected drive positions among which the selector lever 15 moved. A locking bolt, actuated by an electrical solenoid for movement parallel to the axis of the selector shaft, includes a ramp contacted by a spring-loaded bolt mounted for movement laterally with respect to a second bolt, held by a compression spring in contact with the selector lever.
