A power transmission mechanism has a variable ratio belt drive input 36, 66, 68, a pair of interconnected simple planetary gear sets 98, 110 and a differential gear set 140. The interconnected planetary gear sets are controlled by a pair of selectively engageable friction brakes 142, 116 to provide either a forward drive ratio or a reverse drive ratio. These brakes are designed to be slippingly engaged for smooth starting. The differential gear set has an input member 136 connected to the output of the planetary gear sets and a pair of output members 168, 170 which are connected to drive axles adapted to be connected to vehicle drive wheels. The belt drive, planetary gear sets and differential gear set are enclosed in a threepiece housing 28, 30, 32 which is adapted to be connected to an engine. The componont are arranged within the housing for use in a transverse engine drive system.
