Abstract
An improved seal assembly is provided that minimizes loss of transmission pump pressure by controlling fluid flow past a torque converter hub bushing to meet bushing lubrication requirements without unnecessarily diminishing pump pressure and while also minimizing frictional losses. The seal assembly includes a rigid carrier adapted to fit between a pump body member and the torque converter hub. An elastomeric lip extends from the rigid carrier. A contact layer is connected to the elastomeric lip and configured to sealingly contact the torque converter hub. The contact layer is integral with and harder than the elastomeric lip, therefore minimizing frictional losses.
