ABSTRACT:
An improved vehicular change gear transmission (100) is provided that includes a mainshaft thrust washer (32) having at least one and preferably a plurality of substantially equally circumferentially spaced depressions (48) on at least one side and preferably indexed with substantially equally circumferentially spaced depressions (58) on the opposite side thereof that are adapted to enable lubricant (9) to move radially outwardly from between mainshaft gear thrust surfaces (47, 49) disposed on opposite sides of thrust washer (32) to minimize accumulation of lubricant (9) therebetween resulting in reduced hydrodynamic drag.
