机油冷却器的回油流经管路进入壳体组件 (3) 上的进油口 (2)。 流经油道 (4) 的机油流入油道 (5)。

流经油道 (5) 的机油流入储油室 (6)。

储油室 (6) 中的机油流入 1 号行星齿轮轴 (7)。 1 号行星齿轮轴 (7) 有使机油能够流向轴承的钻孔油道。 机油将流向轴承的四周。 然后,机油流经耦合孔 (8) 以帮助润滑 1 号离合器的盘和板。

储油室 (9) 中的机油流入 2 号和 3 号行星齿轮轴 (10)。 2 号和 3 号行星齿轮轴有钻孔油道,能使机油流到轴承。 机油流过轴的轴承,然后经过齿圈 (11) 和 (12) 中的孔。 随后机油润滑 2 号和 3 号离合器的盘和板。

储油室 (9) 的机油润滑轴承 (13)。 储油室 (9) 的机油还流过支架中的油道 (14)。 机油还润滑 2 号离合器的盘和板。

油道 (15) 中的机油流至输入轴和输出轴之间的区域。 该机油润滑轴承 (16) 和 (17)。

机油从输入轴和输出轴之间的区域流经油道 (18)。 部分这种机油润滑轴承 (19)。 机油从油道 (18) 流入储油室 (20) 和 (21)。 储油室 (20) 中的一些机油流入 4 号行星齿轮轴 (22)。

4 号行星齿轮轴 (22) 有使机油能够流向轴承的钻孔油道。 机油将流向轴承的四周。 然后,一些机油流向轴承 (19)。

机油从储油室 (21) 流经旋转轮毂 (23) 的孔以润滑 5 号离合器盘和板。 然后,机油流经齿圈 (24) 上的孔以润滑 5 号离合器的盘和板。

储油室 (25) 内的机油润滑轴承 (26)。 储油室 (25) 中的大部分油流入 6 号行星齿轮轴 (27)。

6 号行星齿轮轴 (17) 有使机油能够流向轴承的钻孔油道。 机油流向行星齿轮轴轴承四周,流经齿圈 (28) 的孔。 该机油润滑 6 号离合器的盘和板。
