All outlet oil from the torque converter oil cooler goes through a line to oil inlet port (20) on housing assembly (1). The oil goes through passage (18) in housing assembly (1). Some of the oil that flows through passage (18) flows into passage (17). From passage (17), the oil flows to bearing (15) .
Some of the oil that flows through passage (18) flows into oil chamber (2) at the front of the transmission.
Some of the oil from oil chamber (2) flows to the Number "1" planetary shafts (22). Number "1" planetary shafts (22) have drilled passages which allow the oil to flow to the bearings. The oil flows around the shaft bearings. Then, the oil flows through holes in coupling (21) in order to help lubricate the discs and the plates of the Number "1" clutch.
The rest of the oil from oil chamber (2) flows into passage (4) in the reverse carrier. Some of this oil flows through passage (3) in order to lubricate the discs and the plates of the Number "1" clutch. The rest of the oil from passage (4) fills oil chamber (23) .
Some of the oil from oil chamber (23) flows to the Number "2" and "3" planetary shafts (24). Number "2" and "3" planetary shafts (24) have drilled passages in order to allow the oil to flow to the bearings. The oil flows around the shaft bearings. Then, the oil flows through holes in ring gears (25) and (26) in order to help lubricate the discs and the plates of the Number "2" and Number "3" clutches.
Oil from oil chamber (23) lubricates bearing (6). Oil from oil chamber (23) also flows through passage (5) in the carrier in order to lubricate the discs and the plates of the Number "2" clutch.
Some of the oil from passage (18) also flows through passage (13) of the input shaft. Next, the oil flows into the area between the input shaft and the output shaft. This oil lubricates bearings (7) and (16) .
Oil flows from the area between the input shaft and the output shaft through passage (27). Some of this oil lubricates bearing (8). From passage (27), the oil flows into oil chambers (29) and (31). Some of the oil in chamber (29) flows into Number "4" planetary shafts (28) .
Number "4" planetary shafts (28) have drilled passages which allow the oil to flow to the bearings. The oil flows around the shaft bearings. Then, some of the oil flows to bearing (8) .
Oil flows from oil chamber (31) through holes in rotating hub (9) in order to lubricate the discs and the plates of the Number "5" clutch. Then, this oil flows through holes in ring gear (30) in order to lubricate the discs and the plates of the Number "4" clutch.
Some oil from passage (18) flows through passage (10). The oil in passage (10) fills oil chamber (12). The oil in oil chamber (12) lubricates bearing (14). Most of the oil in oil chamber (12) flows to Number "6" planetary shafts (19) .
Number "6" planetary shafts (19) have drilled passages which allow the oil to flow to the bearings. The oil flows around the planetary shaft bearings and flows through holes in ring gear (32). This oil lubricates the discs and the plates of the Number "6" clutch.
The restrictions inside the transmission keep the lubrication pressure of the warm oil at approximately 140 kPa (20 psi).
All leakage oil from the clutches and return lubrication oil goes to the bottom of the transmission case. This oil goes to the main oil reservoir in the output gear case.

All outlet oil from the torque converter oil cooler goes through a line to oil inlet (29). The oil goes through passage (28) to passage (21) in the input shaft. Some of the oil in passage (28) goes through passage (25) in order to lubricate bearing (23).
The oil from passage (28) flows to planetary shafts (27). Planetary shafts (27) have drilled passages which allow the oil to flow to the bearings. The oil flows around the bearings for the planetary shafts. Oil also flows from the holes in the ends of planetary shafts (27). Then, the oil flows to bearings (4) and (26). Oil also flows through internal passages in order to lubricate the discs and the plates of the Number "2" clutch.
Oil from passage (28) fills oil chamber (18). Oil flows from oil chamber (18) through passage (20). From passage (20), the oil flows through holes in coupling (1) and ring gear (3) in order to lubricate the discs and the plates of the Number "1" clutch.
Oil flows from passage (21) in the input shaft into the area between the input shaft and the output shaft. This oil lubricates bearing (7). Oil flows from the area between the shafts through passage (32) and into oil chamber (9). The oil in oil chamber (9) lubricates bearings (10) and (31). The oil in oil chamber (9) also flows into planetary shafts (30) and (33) .
Planetary shafts (30) have drilled passages which allow the oil to flow to the bearings. The oil is also used to lubricate the discs and the plates of the Number "3" clutch.
Planetary shafts (33) have drilled passages which allow the oil to flow to the bearings. The oil is also used to lubricate the discs and the plates of the Number "4" clutch.
The oil in the area between the input shaft and the output shaft also flows through passage (22). From passage (22), the oil flows through passage (34).
