Abstract
A transmission ECU calculates a differential rotation, which is the rotational speed difference between a friction plate and a separator plate, when it is determined that a second brake is not engaged. If it is determined that the differential rotation is equal to or above a predetermined value, the transmission ECU narrows the pack clearance of the second brake. If it is determined that the differential rotation is less than the predetermined value, the transmission ECU widens the pack clearance of the second brake.
