Operation - When the selector lever (80) is moved away from position "N" to position "D", the roller (84)
locks in position engages in the recess (69d) in the locking disc via the cam (69). See Fig. 87. The selector lever
(80) is locked to prevent longitudinal movement. Now it can only be shifted out of selector lever position "D"
against the force of the leaf spring (85). It is still possible to move the selector lever (80) sideways (touch shift
in the "+" and "-" direction).
