Oil comes from oil cooler ( 12) through an oil line to
lubrication relief valve (6). Oil from the lubrication relief
valve goes into passage (14) and gives lubrication to the
planet gears, discs, plates and bearings of No. 1 clutch
(17), No. 2 clutch (18) and No. 3 clutch (19) through a
common passage. Oil for lubrication of the components
of No. 4 clutch (20) and No. 5 clutch (21) comes from
leakage. No. 6 clutch (22) gets oil for lubrication from
tube (15). Tube (15) also sends oil for lubrication of the
transfer gears.
The normal leakage of oil from the torque converter
goes into the reservoir in bottom of torque converter
housing (I1). The scavenge pump pulls the oil through a
screen (10), through the pump and sends the oil to the
reservoir for the transmission.
