(28) Ring gear for No. 6 clutchReturn oil from the oil cooler goes through a line to oil inlet port (2) on housing assembly (3). Oil that flows through passage (4) flows into passage (5).Oil that flows through passage (5) flows into oil chamber (6).Oil from oil chamber (6) flows to the No. one planetary shafts (7). No. One planetary shaft (7) 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 (8) in order to help lubricate the discs and the plates of the No. one clutch.Oil from oil chamber (9) flows to the No. two and three planetary shafts (10). No. two and No. three planetary shafts have drilled passages in order to allow the oil to flow to the bearings. The oil flows around the shaft bearings
