Abstract
A torque converter is provided. The torque converter includes a damper assembly and a turbine assembly connected to the damper assembly. The turbine assembly includes an axially movable turbine piston, a spacer plate fixed to the turbine piston and a bias spring. The spacer plate retains the bias spring on the turbine piston with a preload force. A method of forming a torque converter is also provided. The method includes providing a bias spring contacting a front cover side surface of a turbine piston; and fixing a spacer plate to the turbine piston such that the spacer plate holds the bias spring against the front cover side surface of the turbine piston.
