All of the outlet oil from the power train oil cooler flows to a manifold on the input gear housing. Oil flows through the manifold to main oil passage (14) in the transmission input shaft.
Lubrication oil flows to the input transfer gears and to the output transfer gears. This oil flows through a passage in the manifold on the input transfer gear housing.
Oil flows through passage (10) in order to lubricate the splines on the transmission input shaft.
The oil from passage (8) flows to passage (15) in the Number 1 carrier. Some of the oil flows through passage (17) in order to lubricate the bearing on the Number 1 carrier. The remainder of the oil flows to a passage in Number 1 planetary shaft (18). Number 1 planetary shaft (18) has drilled passages that allow some of the oil to flow to the bearings.
From the passage in the Number 1 planetary shaft, oil flows through a drilled passage in pin (19) to holes (2) in the Number 1 ring gear. Holes (2) allow oil to flow to the Number 1 clutch discs and plates.
The oil from passage (1) flows to passage (4) in the Number 1 sun gear. Some of the oil lubricates the bearing on the Number 2 sun gear. Some of the oil flows to passage (20). Passage (20) directs the oil to a passage in Number 2 planetary shaft (23) and Number 3 planetary shaft (23). Planetary shaft (23) has drilled passages that allow the oil to flow to the bearings.
The remainder of the oil from passage (20) flows to the drilled passage (21) in the Number 2 carrier and in the Number 3 carrier. The oil flows from passage (21) to passage (22) in the coupling gear. Passage (22) allows the oil to flow to holes (3) in the Number 2 ring gear. The holes in the ring gear allow the oil to flow to the Number 2 clutch discs and plates.
The oil from passage (5) flows to the space between the transmission input shaft and transmission output shaft (11). The oil travels along the splines toward the output end of the transmission.
Some of the oil flows through passage (6) to the bearing on output shaft (11). The remainder of the oil from passage (6) flows to passage (16) in the Number 4 carrier. The oil in passage (16) flows to a passage in Number 4 planetary shaft (25). Planetary shaft (25) has drilled passages that allow the oil to flow to the bearings.
Some of the oil that travels along the space on the inside of output shaft (11) flows to passage (7). The oil then flows through passage (9) to holes (26) in the rotating hub. The holes in the rotating hub allow the oil to flow to the Number 5 clutch discs and plates.
The remainder of the oil that travels along the space on the inside of output shaft (11) flows to passage (13). Passage (13) directs oil to passage (12) .
The splines on the output shaft and on the shaft for the parking brake receive lubrication oil through passage (12) .
The oil that is sent for lubricating the clutches and for cooling the clutches drains to the bottom of the transmission case. The return oil from the input transfer gears also drains to the bottom of the transmission case. An elbow is connected to the bottom of the transmission case. The oil in the bottom of the transmission case flows through the elbow to the main oil reservoir in the output transfer gear case.
