SIMPLIFIED AUTOMATIC TRANSMISSION SHIFTER

摘要

An automatic transmission shifter for a vehicle comprises a unitary glass reinforced nylon housing open at the bottom and having interconnected, spaced upper, side and end walls. A slot is formed in the upper wall, a pair of spaced aligned apertured bosses are formed in the side walls, and integral flanges extend from the side and end walls and incorporate a plurality of spaced apertures for mounting the housing to vehicle structure. A pair of spaced, aligned position control plates, each comprising a plurality of notches, are formed interiorly on the side walls, a plurality of detent notches are formed interiorly on the housing on one of the side walls below the position control plates, and a shift cable access opening is formed in one of the end walls. A shift lever assembly including an operating lever extends upwardly through the slot. A plastic trunnion mounts the lever and a pivot pin carried by the boss apertures mounts the trunnion for pivotal movement of the lever among a plurality of transmission control positions. The ends of a position pin mounted centrally on the shift lever simultaneously engage notches in each position control plate to control lever movement between positions. A spring-biased detent ball mounted on the trunnion engages in the detent notches to locate the lever in each of the control positions.
