Operation

The reverse and parking lock solenoid (Y66/1) is actuated via the ETC control module (N15/3) and moves the
lever (69a) in the direction of the cam (69b) so that the shift shaft (66) is blocked. See Fig. 151. When de-
energized, the support lever (69c) holds the lever (69a) in position to prevent it from engaging by itself when
exposed to severe shocks.
