Abstract: The integrated controller calculates the required lubricant flowrate required for lubricating the friction element corresponding to a selected position on the basis of a rotation speed difference in the friction element corresponding to the selected position, and increases the lubricant flowrate supplied to the friction element corresponding to the selected position immediately after switching is made between the forward position and the reverse position and supplies the lubricant flowrate larger than the required lubricant flowrate to the friction element corresponding to the selected position.

Abstract: In a cooling structure in a clutch having drive plates and driven plates, a lower limit of a width of each of dot grooves is set to a width a at which a flow quantity of lubricating oil passing through each of the dot grooves becomes a minimum flow quantity at which the drive plates and the driven plates can be cooled to a temperature equal to or lower than an upper limit temperature (Tmax) and an upper limit of the width of each of the dot grooves is set to a width b at which an air content in lubricating oil passing through each of the dot grooves becomes a maximum air content at which, according to lubricating oil having the air content, the drive plates and the driven plates can be cooled to a temperature equal to or lower than the upper limit temperature (Tmax).
