ABSTRACT OF THE DISCLOSURE Shift mechanism for a transmission is provided for en- gaging and disengaging a gear therein. The mechanism is particu- larly designed to disengage the geat even when the transmission is under a heavy load. The shift mechanisam includes a clutch dog or collar on a shift with the collar having at least one lug or projection which is engagable with and disengagable from a lug or projection on a gear rotatably carried on the shaft. One of the collar and gear has a recess adjacent its respective lug in which a ball is located with the ball also being retained by a retaining ring mounted on the collar or gear. When the collar and a gear are in an engaged position, both lugs are in contact with the ball; when the collar is moved away from the gear to disengage the collar and the gear, the point contact of the lugs and ball enables disengagement of the collar from the gear even when the transmission is under a heavy load.
