An oil hydraulic circuit includes a B2 apply control valve establishing communication between a second feedback oil channel connected to a feedback pressure chamber and a drain port, and between a D 1st speed oil channel and a drain port when SL pressure is supplied, and a B2 control valve cutting off an R-range pressure oil channel from a B2 oil channel, and establishing communication between the B2 oil channel and the D 1st speed oil channel when SLU pressure is supplied. An ECU turns on a solenoid (SL) to supply SL pressure to the B2 apply control valve, and turns on a linear solenoid (SLU) to supply SLU pressure to the B2 control valve, when the shift lever is set at the R position during forward running.
