ABSTRACT:
In order to prevent the line pressure level from being adjusted to abnormally low levels during the operation of a high load device such as an air conditioner compressor, oil pump and the like, which device consumes energy output from the engine and reduces the amount of torque which is supplied to the input shaft of the transmission, the adaptive correction of the line pressure level is inhibited while the high load device or devices are sensed as being in use.
