Rear of scraper transmission (1) Transmission oil filter (2) Transmission oil pump (3) Transmission scavenge pump (4) Transmission transfer gear housing (5) Transmission oil tank (6) Transmission scavenge screen (7) Magnetic oil screenThe transmission oil pump is a two-section pump. The transmission scavenge pump section (3) is on the cover end. The transmission oil pump section (2) is on the drive end. The pump is driven by the transmission output gear which is located inside the transmission transfer gear housing (4). Oil for the scavenge section is delivered from the reservoir of the differential case through the transmission scavenge screen (6). Transmission scavenge pump section (3) delivers the oil to the transmission oil tank (5). Oil for the transmission oil pump section (2) is delivered from the reservoir of the transmission oil tank (5). The oil flows through magnetic oil screen (6). The oil then flows through pump (2) and transmission oil filter (1) to the selector control valve in the transmission. The oil is then directed to the pressure control valve. Part of the oil flows to the transmission clutches. Part of the oil flows to the torque converter inlet valve.
