PURPOSE:To prevent the speed change performance of an automatic transmission from being varied due to the variation of characteristics of a control device and control parts of an automatic transmission gear main body. CONSTITUTION:A characteristic storage device 16 is installed in an automatic transmission main body 10. The characteristics of elements for exerting influence to the speed change performance of a solenoid 12, a sensor 14 and the other members are stored in the characteristic storage device 16. An electronically control device 18 corrects the contents of control according to a signal input from the characteristic storage device 16. Thus, the variation of speed change performance of the automatic transmission gear can be decreased. |
