The transmission mainshaft thrust washer and retainer ring combination has radially inward extending flanges of a pair of adjacent mainshaft gears selectively clutchable with the mainshaft are prevented from moving axially away from each other by first and second retainer rings respectively disposed in annular grooves adjacent sides of the respective gear flanges which face away from each other. They are prevented from moving axially towards each other by a thrust washer disposed in an annular groove in the mainshaft between sides of the respective gear flanges which face towards each other and operative to transmit axial thrust to the mainshaft during the process of clutching the respective gears. The first and second retainer rings are interchangeable with each other but not with the thrust washer as a result of both retainer ring grooves having respective axial widths that are the same as each other and wider than the axial width of the thrust washer groove axial width. |
