ACTIVE ELECTROMECHANICAL ARMATURE ASSEMBLY FOR AN AUTOMATIC TRANSMISSION

摘要

An active electromechanical armature assembly for a transmission is provided. The active electromechanical armature assembly improves fuel economy by storing transmission fluid in areas away from rotating components during hot operation. During other conditions the transmission fluid is kept in the sump. The active electromechanical armature assembly includes a moveable armature or plunger. Movement of the plunger controls the opening and closing of an opening that communicates between the sump and the side or front cover of the transmission.
