Lokar 727 Kickdown Installation

The kickdown switch in the Chrysler 727 shifts the automatic transmission into a lower gear when the accelerator is pushed hard to the floor. This boosts torque from the transmission to accommodate the sudden increase in engine power output. The action of the kickdown switch is commonly known as "passing gear" because it provides a burst of extra speed in situations such as pulling out to pass a car ahead. In the Chrysler 727, the kickdown switch is a manual, cable-actuated mechanism. The Lokar 727 Hi-Tech Kickdown switch replaces some factory kickdown assembly components with aftermarket substitutions.

Instructions

    1

    Bolt the Lokar spring return bracket to the transmission housing. Mount the kickdown adjuster bracket on the spring return bracket.

    2

    Mount the kickdown cable bracket to the bolt hole in the transmission tail housing where it mates with the transmission case.

    3

    Insert the ball fitting on the end of the kickdown cable into the mounting hole on the larger tang of the OEM transmission kickdown lever. Secure with the supplied screw.

    4

    Feed the braided cable housing of the kickdown cable up to the threaded adjuster at the kickdown adjuster bracket. Leave 1 inch of extra length on the cable and trim off the outer housing to the desired length.

    5

    Insert the hex carb fitting assembly, including the plastic Lokar cable slide fitting, into the hole in the smaller tang on the original kickdown lever. Install the teardrop spring retainer on the opposite side of the tang and secure the assembly with the supplied screw.

    6

    Insert the inner cable into the the Lokar cable slide fitting and place the cable stop on the cable about 1 1/2 inches from the hex fitting. Cut off excess cable about 1 inch beyond the cable stop.

    7

    Hold the throttle all the way open and pull the kickdown inner cable tight. Slide the cable stop against the Lokar cable slide fitting and tighten the cable stop Allen screw.

    8

    Make sure the carburetor-throttle linkage operates without binding after the kickdown switch is installed. Test-drive the vehicle.
