<p>PURPOSE:To eliminate the fluctuation of speed change performance by providing a characteristic memory device to store the characteristics of a controller and control parts in the casing of a select position switch, and connecting the characteristic memory device to an electronic controller through the signal lines of the select position switch. CONSTITUTION:This automatic transmission body 10 is provided with a plurality of solenoids 12 for controlling speed change and hydraulic pressure, and these solenoids 12 are controlled by an electronic controller 18 based on the output signals from various sensors 14 and a select position switch 17. In this case, a characteristic memory device 16 is provided in the casing side section of the select position switch 17. This characteristic memory device 16 as a memory means comprises an IC memory and a variable resister and the like to store the characteristics of the solenoids 12 and various sensors 14 and hydraulic pressure rising characteristics of a friction engaging element. The output signal of the characteristic memory device 16, which input the signals from the P position 20 of the switch 17 and ignition, is output to the electronic controller 18 from an R position 22 through signal lines.</p> |
