Transmission General Description Synchronizers

The transaxle is designed for the use with transverse-mounted engines, and therefore incorporates the differential. It is similiar to other transaxles in its general construction features. The case is made of aluminum for a high strength-to-weight ratio. The design incorporates the familiar parallel dual shaft arrangement which minimizes weight and conserves space. All forward gears are synchronized, while reverse uses the sliding idler gear arrangement. The synchronizers for 1st and 2nd gears are located on the output shaft. The input shaft carries the synchronizers for 3rd, 4th, and 5th gears. This proven design offers good shift feel with low idling noise.

Transmission General Description 5th and Reverse Gearshift Cam

The following components operate together in order to prevent the gearshift control lever from being shifted from 5th gear directly to reverse:

When the gearshift control lever shifts to 5th gear, the 5th and reverse gearshift cam turns clockwise with the gearshift and select shaft. The cam guide return spring pushes the 5th and reverse gearshift cam upward. The 5th and reverse gearshift shaft meets the 5th to reverse interlock guide bolt at this location. Then the 5th and reverse gearshift cam cannot turn any further. A 5th to reverse gear shift is no longer possible when the 5th and reverse gearshift cam cannot turn.

Shifting from 5th gear to neutral is possible when a reverse gear shift remains canceled. When the gearshift and select shaft moves to the neutral position between 3rd and 4th gears, the 5th and reverse gearshift cam cancels. Moving the gearshift control lever to the position between the 5th and reverse causes the following conditions:

The gearshift and select lever can now move to the reverse position without interference from the 5th and reverse gearshift cam.
