Fine filter:
To avoid cavitation, the converter must be always completely filled with oil.
This is achieved by a converter pressure back-up valve, rear-mounted to the
converter, with an opening pressure of about 5 bar.
The oil, escaping out of the converter, is directed to a heat exchanger.
From the heat exchanger, the oil is directed to the transmission and there to the lubricating oil circuit so that all
lubricating points will be supplied with cooled oil.
In the electrohydraulic control unit, 6 pressure regulators are installed
(See the section: Electro hydraulic shift control)
The allocation of the pressure regulators to the single gears can be seen on the Clutch chart.
