This patent describes a controlled slip torque converter and clutch comprising; an input shell; a torque converter means having an impeller drivingly connected with the input shell, a turbine and a stator disposed for toroidal flow, the torque converter means transmitting drive torque from the impeller to the turbine in a slipping relation; clutch means engageable in response to fluid pressure to limit the slip relation between the impeller and turbine and being disposed in drive relation between the input shell and the turbine and cooperating therewith to form clutch apply chamber means and clutch release chamber means; variable flow restriction means including spring means disposed between the clutch apply chamber means and the release chamber means for providing a controlled flow from the apply chamber means to the release chamber means; and viscous damper means disposed in parallel relation with the spring means on the variable flow restriction means and being responsive to torque disturbances at the clutch means and the turbine to restrict the rate at which the flow restriction means varies.
