For 1990-2009 cars

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

• | The 5th and reverse gearshift cam and return spring

• | The gearshift interlock plate

When the gearshift control lever shifts to 5th gear, the 5th and reverse gearshift cam (7) turns clockwise with the gearshift and select shaft (1). The cam guide return spring (3) pushes the 5th and reverse gearshift cam (7) upward. The 5th and reverse gearshift shaft meets the 5th to reverse interlock guide bolt (2) at this location. Then the 5th and reverse gearshift cam (7) cannot turn any further. A 5th to reverse gear shift is no longer possible when the 5th and reverse gearshift cam (7) cannot turn.

Shifting from 5th gear to neutral is possible when a reverse gear shift remains canceled. When the gearshift and select shaft (1) moves to the neutral position between 3rd and 4th gears, the 5th and reverse gearshift cam cancels (6). Moving the gearshift control lever to the position between the 5th and reverse causes the following conditions:

• | The gearshift and select shaft (1) moves upward.

• | The 5th and reverse interlock guide bolt (2) holds the 5th and reverse gearshift cam (6) stationary.

The gearshift and select lever (5) can now move to the reverse position without interference from the 5th and reverse gearshift cam (6).
