A transmission includes an input shaft that couples to a prime mover, twin countershafts and a main shaft having gears coupled thereon, an output shaft that selectively provides a torque output to a driveline, a first shift actuator that selectively couples the input shaft to the main shaft. The transmission includes a second shift actuator that couples the main shaft to the output shaft with a selected reduction ratio, and a controller including a vehicle state circuit that interprets at least one vehicle operating condition, and a neutral enforcement circuit that provides a first neutral command to the first shift actuator and a second neutral command to the second shift actuator, in response to the at least one vehicle operating condition indicating that vehicle motion is not intended.

There is provided a shift device including: a shift body configured to be moved by being pivoted or slid to change a shift position; and a locking mechanism provided with a lock member, the lock member being displaced from one side of a movement direction of the shift body to lock movement of the shift body from a predetermined shift position toward both sides in the movement direction.

There is provided a shift device including: a shift body configured to be moved to change a shift position; a first locking mechanism provided with a first lock member, the first lock member being disposed at a first locking position to lock movement of the shift body from a first shift position; and a second locking mechanism provided with a second lock member, the second lock member being disposed at a second locking position to lock movement of the shift body from a second shift position.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.

A rotational angle sensor detects the rotational position of a motor and outputs a motor rotational angle signal corresponding to the rotational position of the motor. An output shaft sensor detects a change in the magnetic field of a target that rotates integrally with an output shaft to which the rotation of the motor is transmitted, and outputs an output shaft signal according to the rotational position of the output shaft. A shift range control unit includes a motor control unit.

In a shift device, when a lock lever is disposed at a restriction position or an intermediate position, a detent groove of a lever is abutted by the lock lever, and pivoting of the lever from a D position toward an S position, and pivoting of the lever from the S position toward the D position, is restricted. However, when the lever is disposed at the D position or the S position, by moving the lock lever to a permitted position, the detent groove does not abut the lock lever and so pivoting of the lever from the D position toward the S position and pivoting of the lever from the S position toward the D position is permitted. Thus, pivoting of the lever from the D position toward the S position and pivoting of the lever from the S position toward the D position can be restricted and permitted.

A shift lever assembly for a vehicle includes a housing having an inner space and an open part. The open part is provided at a lower part of the housing and is open in upward and downward directions. A shift lever is rotatably mounted in the inner space by being inserted into the inner space from a lower side to an upper side of the inner space through the open part. A bracket is assembled with the lower part of the housing to close the open part and allowing the housing to be fixed to a vehicle body.

A control unit is provided for an automatic transmission of a vehicle. The vehicle has a gear selection operating element which allows a user of the vehicle to set different gear stages of the transmission by actuating the gear selection operating element, and the vehicle has at least one setting operating element which allows the user to change the value of a parameter of a function of the vehicle by actuating the setting operating element when the function of the vehicle is activated. The control unit is designed to detect an actuation of the gear selection operating element for a period of time which is equal to or longer than a minimum duration and to determine that the function of the vehicle is deactivated. In response thereto, the control unit is additionally designed to allow a manual change of the transmission gear by actuating the at least one setting operating element.
