Low level of liquid can be the reason of many malfunctions as air gets to liquid, and the liquid suspension with air becomes compressed that leads to chaotic change of pressure and violation of work of couplings and tape brakes.
Also increased level of liquid leads to the fact that the rotating gear wheels of the transmission shake up foam which results in the same results, as the air which got to transmission liquid.
Anyway vials of air lead to an overheat and oxidation of transmission liquid which, getting in the valve, breaks work of coupling and brakes. Foaming can lead to a liquid effluence which can be accepted for liquid leak. |
