ABSTRACT:
A V-belt continously variable transmission includes a torque converter shiftable between a lock-up state and a non lock-up state. A pulley unit includes a driver pulley, a follower pulley, and a V-belt drivingly interconnecting the driver and follower pulleys. At least one of the driver and follower pulleys is hydraulically actuated in response to a line pressure to induce a force which the V-belt is gripped with by the pulley. The line pressure control system is constructed and arranged such that the magnitude of the line pressure is increased when the torque converter is in the non lock-up state.
