ABSTRACT:
A shifting device for an automatic transmission of a vehicle has a manual shift mode which permits a driver to manually change a speed ratio by displacing a shift lever in an upshift direction or a downshift direction in a manual operation lane from its neutral position. The shifting device is provided with a switch for detecting that the shift lever has moved to the manual operation lane, a switch for detecting that the shift lever has moved in the upshift direction from its neutral position, and a switch for detecting that the shift lever has moved in the downshift direction from its neutral position. All these three switches comprise a traveling contact and two contacts. The traveling contacts of the three switches are earthed, and the six contacts of the three switches are respectively connected to six input terminals of a control unit. Due to this, the control unit can determine a fault in any of the switches based on the signals input into the input terminals.
