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.

A control cable adjusting arrangement for a gear shift locking arrangement includes a holder portion which accepts an inner cable of a control cable in one end thereof. An outer cable encasing the inner cable is retained by a bracket. The other end of the holder accepts an end of a control rod associated with a gear shift lever. Disposed around the holder is a slider portion movable between a locked and unlocked position determined between two stopper flanges formed on the outer circumference of the holder. The holder and slider are made of an elastic material such as rubber and an end of the holder which accepts the end of the control rod has a flared outer circumference. When the slider is moved from the unlocked position to the locked position the end of the control rod becomes held firmly in the holder and the end of the inner cable held by the holder is drawn tightly such that slack is removed from the inner cable and the relative positions of the inner cable and the control rod may be adjusted by a simple one touch operation.

Control cable adjusting arrangement

A gear select lever locking arrangement comprises a gear select lever with a position pin and a manual push button for moving the position pin into a predetermined notch of a position plate from a groove of the position plate after placing the gear select lever in a P (parking) position. When the position pin moves into the predetermined notch, a catch mechanism shifts from an open position to a catch position. In the catch position, a latch assumes a position to prevent the position pin from moving out of the predetermined notch. The catch mechanism is operatively connected to a blocking mechanism such that when the catch mechanism assumes the open position, the blocking mechanism assumes a blocking position wherein a key operated cylinder is blocked from rotating a predetermined position wherein a key is removable from the key operated cylinder. When the catch mechanism assumes the catch position, the blocking mechanism assumes an unblocking position wherein the key operated cylinder is allowed to rotate to the predetermined position. The catch mechanism includes a blocking mechanism control lever and a keeper.

Gear select lever locking arrangement

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.

Control device for automatic transmission

In order to eliminate play between the elements of a shift mechanism wherein when a shift lever is moved toward control wire, the control wire is moved toward the shift lever and versa. A torsion spring which produces a force greater than the force which resists movement of the control wire or cable is disposed with a bell crank which interconnects the shift lever and the control wire and is arranged to bias a pin which forms part of the connection between the shift lever and the bell crank into constant engagement with a side of an elongate slot in which the pin is received and which slot forms part of the above mentioned connection.

Shift lever for automatic transmission

A bell crank lever is used to operatively interconnect a transmission control cable with a shift lever. The bell crank lever is pivoted about an axis which is located at essentially the same level but separate from the axis about which the shift lever is pivotal. Connection between the shift lever and the bell crank lever is achieved by means of a pin which projects from one side of a shaft which forms part of a detent mechanism, and an elongate slot formed in one end of the bell crank lever. The bell crank lever is pivotally mounted on a plate which forms part of the detent mechanism and in which detent recesses are formed. This facilitates the accurate assembly of the device. Further, as the bell crank lever is pivoted at substantially the same height as the pivot shaft of the shift lever and arranged above the bottom wall of the base bracket, a lever effect equal to that of the conventional construction is achieved. Furthermore, since there is no need for an intermediate shaft, reduction in play and cost are also achieved.

Shift device for automotive automatic transmission

In a gear selector mechanism for an automatic transmission, a pivotal support of a T-like configuration is provided which consists of a crosswise sleeve and a longitudinal tube. The crosswise sleeve is rotatably installed on a pivot which is installed in a floor panel by way of a base plate. A gear shift lever is installed on the longitudinal tube of the pivotal support for tuning together with same.
