DISPOSITIVO DI CONTROLLO DELLA PRESSIONE DI LINEA SENSIBILE ALLA TEMPERATURA PER CAMBIO AUTOMATICO DI AUTOVEICOLO ED AUTOVEICOLO CHE LO COMPRENDE

摘要

The temperature of the oil (hydraulic fluid) which is used to engage the friction elements of the transmission is sensed. When the temperature exceeds a predetermined level, the level of line pressure which is used during shifting (lower than that used during non-shifting operations) is increased to compensate for the loss in viscosity and lubricative properties of the oil.
