Provided is an automatic transmission which can suppress increase in size. The automatic transmission includes: a transmission mechanism (40) which is disposed in a transmission mechanism storage chamber (4) and has a plurality of transmission elements; a clutch (30) which is disposed in a clutch storage chamber (3), and connects and disconnects power delivery from a driving source to the transmission mechanism (40); and a first control unit (60) which stores first hydraulic control valves (62, 63) that control the transmission mechanism (40), wherein the first control unit (60) is disposed in the clutch storage chamber (3).

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.

A gasket assembly for sealing between a first component and a second component, the first component having a main cavity separated from a secondary cavity by at least one wall, the at least one wall having an aperture formed therethrough, includes a device configured to extend through the aperture. An aperture sealing insert is molded around a portion of the device, the aperture sealing insert sized and shaped to fit into the aperture. An aperture seal is disposed about an outer perimeter surface of the aperture sealing insert, the aperture seal configured to seal against surfaces defining the aperture. A gasket baseplate is configured to be disposed over the aperture sealing insert between the first component and the second component to fluidly seal the main cavity from the secondary cavity while enabling the device to pass through the aperture.

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.

A wheeled vehicle is disclosed. The wheel of the vehicle may be a powered wheeled vehicle with an engine and a transmission system. The transmission system may be used to select a gear ratio to a powered wheel of the wheeled vehicle, such as a single wheel.

The present invention relates to a device for blocking a transmission comprising an actuation mechanism, which is arranged inside the transmission in an at least partially oil-filled transmission chamber, and a drive of the actuation mechanism, wherein the drive is arranged outside of the at least partially oil-filled transmission chamber.

A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion. The body portion is adapted to be removably coupled to the support member. The securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of said retaining bracket.

In an electric oil pump device including a drive power source and a gear device through which a vehicle drive force of the drive power source is transmitted, the electric oil pump device delivering a lubricant oil to the gear device, and generating a hydraulic pressure for controlling the gear device, a pump portion for delivering the lubricant oil, a motor portion for operating the pump portion, and a driver portion for controlling an operation of the motor portion are included. The pump portion, motor portion and driver portion are formed integrally with each other, or the driver portion is disposed adjacent to the motor portion. The pump portion and a part or an entirety of the motor portion are disposed within a space defined by an oil pan and a casing accommodating the gear device, and the driver portion is disposed outside the casing and the oil pan.

An electro-mechanical transmission shifter preferably includes a first actuator, a second actuator, a shift linkage device, actuator mounting bracket, a programmable controller and a gear shift remote. The shift linkage device includes a mounting base plate, a first transmission shifting bracket, a second transmission shifting bracket and a linkage rod. The linkage rod couples the first and second transmission shifting brackets. The actuation rods of the first and second actuators are pivotally connected to the first and second transmission shifting brackets, respectively. A mounting end of the first and second actuators are retained on the actuator mounting bracket with first and second clevis blocks. The programmable controller receives a signal from a gear selector remote to change a gear in a transmission. The programmable controller also monitors the electrical current sent to the first and second actuators.

A wheeled vehicle is disclosed. The wheel of the vehicle may be a powered wheeled vehicle with an engine and a transmission system. The transmission system may be used to select a gear ratio to a powered wheel of the wheeled vehicle, such as a single wheel.
