ABSTRACT:
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.
