Pompa (6) mengirimkan oli bertekanan ke filter oli (4). Minyak melewati filter. Jika elemen filter oli memiliki pembatasan, katup bypass di filter memungkinkan minyak berkeliling filter.Dari saringan oli tersebut masuk ke katup pelepas tekanan (20), katup kontrol aliran (14) dan bermacam-macam (10).

Minyak berjalan melalui bermacam-macam (10) ke katup kontrol hidrolik (11) untuk kopling kemudi dan rem. Minyak ini digunakan untuk operasi dari cengkeraman kemudi dan mekanisme kontrol hidrolik (3) dan (17) untuk rem.

Sejumlah kecil minyak berlangsung dari katup kontrol (11) melalui suatu lubang. Minyak ini adalah untuk pelumasan dari katup kendali, roda gigi kerucut dan bantalan untuk poros roda gigi kerucut.

Minyak untuk katup kontrol aliran (14) melewati katup kontrol aliran. Dari katup kontrol aliran minyak tersebut masuk ke katup kontrol tekanan (15). Minyak ini adalah untuk cengkeraman transmisi. Flow control valve (14) mencegah aliran minyak ke katup kontrol tekanan dari pergi selama sekitar 20 US gpm (75,7 menyala / menit).

Tekanan katup (20) mencegah tekanan dalam sistem dari pergi selama sekitar 425 psi (29,9 kg/cm2). Jika tekanan dalam sistem terlalu tinggi, katup buang membuka dan memungkinkan minyak ekstra pergi ke katup inlet lega (21) untuk converter torsi.
