ABSTRACT:
A transmission has an oil drain passage for connecting an oil reservoir with a mission case in a pump casing. The automatic transmission has also a retainer serving as a shielding member to shield between a discharge opening of the oil drain passage from at least part of a multistage transmission mechanism. This ensures that breather oil blow, which is caused by the spattering and stirring of operating oil by the high-speed drum member, is shielded from at least part of the transmission mechanism.
