ABSTRACT:
A transmission fluid sump for an automotive transmission comprising a reservoir portion, a threaded extension on the reservoir portion and a fill pipe threadably connected to the extension. A closure member seals a central opening in the extension independently of the fill pipe, thereby avoiding overlapping torque windows for the fill pipe and the closure member while providing a single leak flow path for the transmission fluid.
