Abstract

A shifter includes a base and a shift lever pivoted to the base for movement along a single planar shift path. The single planar shift path includes a first portion having P, R, N, and D (i.e. an automatic-shift mode) and a second portion with 4, 3, 2, and 1 (i.e. a manual shift mode). A switch on the shift lever operates a solenoid for changing between an automatic shift mode where the first portion is operable, and a manual shift mode where the second portion is operable. A shift lever position indicator indicates a position of the shift lever in all its positions. The shift lever position indicator includes first and second polarized screens and a first and second polarized light sources arranged to selectively illuminate the first and second indicia when the shift lever is in the automatic or manual shift mode.
