– Lincoln Navigators are equipped with a new 6HP26 transmission. This six speed transmission required a
new style transmission gear selector. This gear selector allows for manual selection of first through fourth
gear, as well as automatic control of first through fourth (O/D disabled) and first through sixth (O/D
enabled). O/D is enabled by moving the gear selector handle to the left while in the D6/D4 gate, and is
disabled by moving it to the right.
