ABSTRACT:
A torque converter clutch has a selectively engageable friction torque transmitting portion and a viscous torque transmitting portion. The friction and viscous portions are serially arranged between a clutch input and a clutch output. Apply pressure enforcing engagement at the friction clutch portion will result in an increase in the torque capacity of the viscous portion when the apply pressure increases. A structural arrangement is provided to increase the apply force of friction portion when the fluid pressure in the viscous portion is increased.
