Means and method for restricting the flow of oil which passes between the front bearing and the main shaft of an automatic transmission for motorized vehicles. A gland is formed at the downstream end of the front bearing in either the inner surface of that bearing or of the housing into which the bearing is press-fitted. A split ring made of thermoplastic material having a pressure velocity value in excess of 20,000 at 100 feet/minute surface speed is inserted in the gland and keyed in place against rotation. The ring has a diameter which is slightly less than the diameter of the main shaft which it surrounds, and has circumferential gaps between its overlapping end portions which extend circumferentially .006"-.300" and has axial dimensions of .006"-.150". The circumference of the ring is spaced radially from the opposed wall of the gland at least .0005".
