ABSTRACT:
Parameter values related to hydraulic pressure characteristics of a solenoid valve in an automatic transmission are stored in a memory associated with a transmission main body. When a transmission control unit for controlling the transmission main body is installed to a vehicle, the transmission control unit retrieves the values from the memory and controls a target current of solenoid valve for realization of a target hydraulic pressure based thereon. The association may be achieved by mounting the memory to the transmission.
