Oil for the lubrication of the transmission comes from the torque converter sump. The transmission lubrication section of the oil pump pulls oil through the suction screen. If the lockup solenoid is activated, the oil combines with the signal oil that is flowing from the lockup and synchronizing valve. The combined oil flows to the transfer case and the oil divides. Some of the oil remains in the transfer case and some of the oil flows to the transmission. Pressure is controlled by a relief valve in the transmission case.
Oil that remains in the transfer case lubricates the transfer gears and the bearings. Some of this oil flows through passage (30) to the back of balance piston (1) for the clutch number 1 . This oil then goes through passage (29) and through passages in ring gear (27). This oil lubricates clutch number 1 (3).
The oil that flows to the transmission flows through passage (6) to center shaft (5). Some of the oil flows forward and some of the oil flows toward the output end. Part of the oil that flows forward goes to the back of balance piston (25) for the clutch number 2 . Some of this oil lubricates ring gear (26) and clutch number 2 (4). Some of the oil that flows forward from passage (6) flows through passages to planetary carrier (28) for the lubrication of planetary gears (2). The remainder of the oil that flows forward from passage (6) flows around center shaft (5) and into the center of center shaft (5).
Part of the oil that flows toward the output end from passage (6) goes behind balance piston (24) for the clutch number 3 . Some of this oil lubricates coupling hub (23) and clutch number 3 (7). The remainder of the oil that flows toward the output end from passage (6) lubricates sun gear (8). Some of the oil flows from sun gear (8) through planetary carrier (21) for the lubrication of planetary gears (20). Some of the oil flows from sun gear (8) for the lubrication of ring gear (11) and clutch number 5 (12). Some of the oil flows from the sun gear (8) through the planetary carrier and output shaft (16) for the lubrication of planetary gears (19). The remainder of the oil lubricates ring gear (9) and clutch number 4 (10).
The remainder of the oil that enters the transmission through passage (6) flows into passage (22). This oil helps lubricate clutch number 4 (10), clutch number 5 (12), and clutch number 6 (13). This oil then flows into slinger (14). The oil is directed to passages that are in planetary carrier (15). This oil lubricates planetary gears (17), ring gear (18), and clutch number 6 (13).
