An electric hydraulic pump for a transmission includes: a motor including a motor cover, a motor case coupled with the motor cover, and a stator and a rotor disposed within the motor cover and the motor case; and a pump including a pump case forming a pump chamber, and a gear rotor which is disposed within the pump chamber, connected with the rotor through a motor shaft and receives rotational power of the motor. In particular, a plurality of oil circulation holes are formed in the motor cover and a connecting hole is formed in the motor cover corresponding to the pump case, and an oil flow channel is formed within the pump case for connecting the connecting hole and an oil inlet of the pump chamber.

Disclosed is a method of manufacturing a control finger using metal powder injection molding. In particular, a metal power and a binder are mixed to obtain a base material for injection molding. Then a molded body is formed by injecting the base material into a mold in a shape of the control finger, using a nozzle. The molded body is then degreased and sintered to form a sintered body from the degreased body. Post-processing is then performed on the sintered body.

A clutch driving device includes a pair of first and second roller wing arms horizontally moving to both sides by moving body moving forward/backward on an axial center line of an actuator and a roller inclined cam surface defining a move path of a pivot is formed such that first and second roller wing arms horizontally move to both sides from the axial center line of actuator, on the surface of a lever generating a stroke at a release bearing. Therefore, the lever can be lifted above a clutch engagement gap where a sufficient stroke is generated at the release bearing engaging a clutch, such that it is possible to achieve sufficient performance even if the output of actuator is reduced by the amount of energy consumption which is relative reduced.
