Abstract
A porous insert for a gearbox or transmission which retards fluid motion and flow within the device when it is subjected to rapid acceleration. The insert may be fabricated of any porous material such as open cell plastic foam, a porous ceramic or sintered metal and is shaped to conform to and is installed in a bottom rear region of the transmission housing. The insert retards motion of the fluid during rapid acceleration, preventing pump starvation and permitting a smaller charge of fluid to be placed in the gearbox or transmission.
