A power train configuration for a continuously variable transmission includes a slippable start clutch located upstream of a belt and sheave system and a pair of non-dynamic forward-reverse clutches located down stream of the continuously variable component. The clutch capacities of the pair of forward-reverse clutches are marginally greater than the maximum torque capacity of the engine but marginally less than the torque at which the belt of the belt and sheave system slips.
