Manual Transmission - Transaxle External Controls / Description and Operation

  1. Selector lever knob
  2. Selector lever
  3. Selector lever housing
  4. Selector lever cables

OVERVIEW

The manual transmission external controls comprise a selector lever assembly and two selector lever cables. The selector lever allows the driver to select 6 forward gears and reverse gear.

The selector lever assembly is located in a central position on the transmission tunnel, between the driver and passenger seats. The assembly is secured to the tunnel with four bolts. The selector lever assembly is a nonserviceable mechanical assembly.

Selections made using the selector lever are passed to the transmission lever arm by two selector lever cables. Ball pins on the selector lever provide for attachment of the selector lever cables. The selector lever has a lift latch which prevents inadvertent selection of reverse gear.

The selector lever assembly is a plastic molded construction and it is supplied as a complete assembly. The selector lever is attached to a gimbal mechanism, which is part of the selector lever, and allows easy movement of the selector lever in the lateral and longitudinal planes.

The selector lever has a ball end to which the selector lever cable is attached. The cable passes all longitudinal movements of the selector lever to the longitudinal lever on the transmission. The selector lever is engaged with a centering spring; the spring returns the selector lever to a position between 3rd and 4th gears when neutral is selected.

The selector lever assembly has a setting pin which engages in a slot in the selector lever. The selector lever plate has a ball end for attachment of the selector lever cable. The selector lever rotates around a pin with lateral movements of the selector lever and passes lateral movements of the selector lever to the selector lever cable and the lateral lever on the transmission.

The two selector lever cables have cable abutments at each end which locate in the selector lever mounting plate and a bracket on the transmission. The selector lever cable is adjustable at the transmission end of the cable. Both selector lever cables have eye ends which locate on the ball ends of the transmission levers and on the selector lever assembly.

The selector lever cable has an adjustment setting mechanism at the transmission end of the cable. The purpose of the mechanism is to accommodate vehicle build tolerances. This ensures that the selector lever movements are correctly aligned with movements of the transmission selector lever. This is essential to ensure the correct operation of the selector mechanism. The longitudinal selector lever cable does not require any adjustment or setting.

SELECTOR LEVER CABLE SETTING PROCEDURE

The correct cable adjustment is achieved by use of a yellow adjustment button at the transmission lever arm eye end of the lateral selector lever cable.

Ensure that the transmission is in neutral and release the yellow adjustment button.

Place the transmission in 4th gear. Insert the locking device into the selector lever mechanism. The locking device holds the selector lever in the 3rd/4th gear plane.

Once the lateral selector lever cable is in the correct position, the yellow adjustment button can be pressed back into the locked position to engage with the serrated portion of the cable.

Check the lateral selector lever cable for the correct setting by selecting all gears.

The cable must be reset whenever any part of the transmission selector has been disturbed or replaced, including the transmission, selector lever cables and selector lever assembly.

OPERATION

Movement of the selector lever in a longitudinal or lateral position, pushes or pulls the lateral and longitudinal levers on the transmission. Movement of the levers into a gear position, operates the shift control mechanism in the transmission, moving selector forks to obtain the required gear ratio.

Reverse gear is inhibited by a manually operated lift latch on the selector lever. The lift latch prevents the selector lever from being moved to the reverse position unless it is raised. When the lift latch is not raised, the selector lever cannot be moved to the reverse position. The selector lever is restricted from being moved to the reverse position by the lift latch being obstructed by the selector lever housing. When the lift latch is raised, a latch on the selector lever is raised allowing the lever to be moved to the reverse position.
