ABSTRACT:
A fluid directing center support is mounted in a main bore of an automatic transmission by means of a pair of intermediate rings between the main bore and the center support. Each intermediate ring includes an elastomeric body portion which is compressed between the main bore and the center support and exerts on the latter balanced and radially directed forces which centralize the center support in the main bore. In addition, the coefficient of thermal expansion of the elastomeric body portion exceeds the coefficient thermal expansion of the transmission case by an amount sufficient to insure that the intermediate ring will always be maintained in compression regardless of the operating temperature of the transmission.
