Abstract
In a power transmission system, a bearing is provided for carrying an output shaft of the torque converter unit. The bearing is lubricated by torque converter fluid delivered thereto through a lubrication circuit. The lubrication circuit includes a flow restriction ring and a drain passage of a relatively large size whereby the life of a fluid seal arranged in the lubrication circuit is remarkably prolonged.
