Abstract: A hydraulic servo assembly includes a piston slidably disposed within a housing and a pin extending from the piston. The pin is interconnected with a servo link rod of the ETRS system. A port enables inlet of hydraulic fluid to induce movement of the piston and the pin from a first position to a second position to pull the servo link rod thereby shifting the transmission range to the out-of-park position. When in the first position the pin biases a forward-reverse enable (FRE) valve of the ETRS system in a first position. When in the second position a bias force of the pin is relieved from the FRE valve enabling the FRE valve to shift to a second position.

Abstract: A motorized beach vehicle has a gear lever clutching structure for prevention of gear slip. The gear lever, the linking arm and the swing arm are connected to form a substantially “h”-shaped structure. The gear lever may be pivoted to combine the combination stud of the swing arm with the combination hole of the combination arm, so that the gear lever may be moved to shift the universal connector of the crank so as to change the speed.

Abstract: Because a shift lever device 10 uses attracting force of a fixed iron core 150A, 216A of a magnet 150 or an electromagnet 216 in switching between a lock state and an unlock state at a shift lock mechanism 118 and a key interlock mechanism 200, the mechanisms can be made compact. When a shift lever 12 is changed from a “D” shift position to a “4” shift position and when the shift lever 12 is changed from a “2” shift position to an “L” shift position, a link 30 is rotated in a same direction. Thus, a sliding direction of a slider 38 which detects a rotational position of the link 30 is only one, and a placement size of a detecting member 48 can be made small and the device can be made compact. Because the shift lock unit 88 is equipped integrally with shift lock mechanism 118, and the link 30, the slider 38 and the detecting member 48 of a sensing mechanism, the shift lock unit 88 can be made compact.

By this arrangement, the shifter senses and shifts based on relative position of the DIM and not absolute position. The shifter is storable and covers can be used to hide it when in the storage position.
