A lock release apparatus includes a gear shift lever assembly including a gear shift lever having a plurality of positions including a parking position, and a detent mechanism shiftable into a detent position wherein said gear shift lever is allowed to move out of the parking position. A lock bushing is supported on the gear shift lever, and has a lock position in which the detent mechanism is prevented from shifting into the detent position and a lock release position in which the detent mechanism is allowed to shift into the detent position. A manual lock release rod is accommodated in a casing secured to the gear shift lever. A screw is fitted into an opening of the casing to prevent an access to the manual lock release, and covered by a lid. The screw is engaged with and disengaged from the opening by using a tool.

Lock release apparatus

A shift lever apparatus for an automatic transmission includes a pin-lock member which can be positioned at a pin-lock position for preventing the positioning pin positioned at the parking position from moving, and a restrict member which can be positioned at a restrict position for preventing the pin-lock member positioned at the pin-lock position from moving. A control device is provided for positioning the pin-lock member at the pin-lock position and for positioning the restrict member at the restrict position when the positioning pin is positioned at the parking position.

Shift lever apparatus

A control device for an automatic transmission is disclosed. The control device is provided with a base member mounted on a vehicle body. A shift lever is pivotably supported by the base member. A guide structure and a check structure and a shaft-locking device are mounted on the base member. The shift lever is provided with a positioning pin movable in the axial direction of the shift lever. A guide structure for guiding the shift lever is provided with a positioning plate having a parking position part and a moving position part engaging the positioning pin. The positioning plate is provided with a buffer member at the moving position part. The check structure for moderating motion of the shift lever has a plurality of positioning recesses on the positioning plate and a check arm for contacting the positioning recesses. The shift-locking device for locking the shift lever is provided with a rotary bushing for blocking disengagement of the positioning pin from the parking position part and a shift-lock solenoid for pivoting the rotary bushing when releasing the shift-lock. The rotary bushing and the shift-lock solenoid are mounted on the base member.
