Abstract
Improved mainshaft gear retainer means for a twin countershaft transmission having floating mainshaft gears positioned close together in groups of two and clutchable to a mainshaft one at a time by positive clutches which each have splines mateable with splines defined by each gear. The improved mainshaft gear retainer means prevents axial movement of two closely positioned gears and includes a snap ring axially interconnecting the gears, a thrust ring interposed between the axially interconnected gears, and a snap ring carried by each axially interconnected gear.
