Abstract
A clutch for an automatic transmission includes a tubular housing surrounding a clutch pack and having an end for engaging with a pressure plate. An annular separator spring on the end provides a biasing force against the pressure plate. A plurality of depressible pins are disposed in the housing and are located radially outward from the annular spring for inhibiting radial movement of the separator spring.
