Abstract
An oil hydraulic circuit includes a Bapply 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 Bcontrol valve cutting off an R-range pressure oil channel from a Boil channel, and establishing communication between the Boil 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 Bapply control valve, and turns on a linear solenoid (SLU) to supply SLU pressure to the Bcontrol valve, when the shift lever is set at the R position during forward running.
