Reverse Lock-Out Device

Shift arm A, the shift arm shaft, and the reverse lock cam lever work as follows to prevent shifting from 5th into reverse:
1. As the transmission is placed in 5th gear, shift arm A is moved down, rotating the cam lever counterclockwise.
2. Once the cam lever is rotated in this direction, the retaining pawl holds the shift arm A in its applied position.
3. Returning the gearshift lever back into neutral rotates the cam lever, freeing the shift arm A to return into neutral.
