The transmission uses a gerotor-type design front pump support and gear. The pump provides the

volume of fluid needed to charge the torque converter, main control assembly, cooling system and

lube system. Pump pressure is regulated by the main regulator valve. The pump has an internal boost

circuit which is more efficient at lower engine speeds.

All fluid drawn from the transmission pan by the pump passes through the filter. The filter and its

accompanying seal are part of the fluid path from the sump (pan) to the fluid pump.
