PCT No. PCT/JP97/02327 Sec. 371 Date Jan. 7, 1999 Sec. 102(e) Date Jan. 7, 1999 PCT Filed Jul. 4, 1997 PCT Pub. No. WO98/01687 PCT Pub. Date Jan. 15, 1998The present invention is a control device and a control method for a transmission with a clutch, by which the clutch is smoothly coupled without generation of shocks or the like in a vehicle. For this purpose, in order to supply a large flow rate initially, a large trigger command value is outputted for a first predetermined period of time to supply a first predetermined quantity to a clutch chamber (8); and before the clutch piston (8A) completes its movement, the large trigger command value is changed to a smaller command value to supply a flow rate which is smaller than that at the time of the first predetermined quantity; and a flow rate detecting valve (20) detects when the clutch chamber (8) becomes full; so that when a period of time, required for making the clutch chamber (8) full, does not fall within a predetermined range of time intervals, a second predetermined period of time, which is a correction of the first period of time by increasing or decreasing so as to cause the period of time, required for making the clutch chamber full, to fall within the predetermined range of time intervals, is outputted to the pressure control valve (10).
