Oil from the transmission oil cooler enters manifold (7) and flows into the input shaft of the transmission. The remainder of the oil flows through passage (8) in the manifold to tube (6) and tube (9) in input gear housing (3).
The oil that flows out of the manifold into tube (6) and tube (9) goes in two directions. The oil flows through tube (6) to tube (5) inside input gear housing (3). The oil also flows to tube (9) which provides oil to the reservoir at the bottom of the input gear housing.
Tube (5) has two holes (4) that spray oil on the two gears as the gears mesh. The oil cools the gears. The oil also lubricates the gears.
The oil flows through tube (9) to the inlet at the base of input gear housing (3). The oil flows through a tube (10) in transmission housing (2) to a passage in output transfer gear housing (1).
One reservoir is behind the idler gear. This reservoir supplies oil to drilled holes in the fixed shaft to supply oil to the idler gear bearings. The other reservoir is behind the drive gear for the secondary steering pump. This reservoir supplies lubrication oil for the bearings for the drive gear and the splines for the secondary steering pump.
Output transfer gear housing (1) is the oil reservoir for the transmission circuit. Tube (11) allows lubrication oil from the output shaft bearings to drain to the reservoir. A hose connects the torque converter housing to the output transfer gear housing. All of the drain oil from the input gears and from the transmission flows through openings in the bottom of the housings to the output transfer gear housing.
