The following components operate together in order to prevent the gearshift control lever from being shifted from 5th gear directly into reverse:
| • | The fifth and reverse gearshift cam, and the return spring |
| • | The interlock plate of the gearshift |
In fifth gear, the fifth and reverse gearshift cam (7) turns clockwise with the gearshift and with the select shaft (1). The cam guide return spring (3) pushes the fifth and reverse gearshift cam (7) upward. The 5th and reverse gearshift shaft meets the interlock guide bolt (2) for 5th-to-reverse at this location. Then, the 5th and reverse gearshift cam (7) cannot turn any further. If the 5th and reverse gearshift cam (7) cannot turn, you cannot shift from 5th gear to reverse gear.
If a shift to reverse gear is cancelled, you can shift from 5th gear to neutral. Shift to the neutral position between 3rd gear and 4th gear in order to cancel the 5th and reverse gearshift cam (6). Moving the gearshift control lever to the position between the 5th and reverse causes the following conditions:
| • | The select shaft (1) moves upward. |
| • | The interlock guide bolt (2) for 5th-to-reverse holds the 5th and reverse gearshift cam (6) stationary. |
You can now move the select lever (5) to the reverse position without interference from the 5th and reverse gearshift cam (6).
