Abstract
A vehicle includes a transmission having a plurality of friction elements selectively engageable to establish power flow paths within the transmission. A controller of the vehicle is programmed to, during a boost phase of a shift, command a first hydraulic boost pressure for a plurality of control loop cycles to an oncoming one of the friction elements (oncoming friction element) and subsequently command a second hydraulic boost pressure less than the first hydraulic boost pressure for only a single control loop cycle that defines an end of the boost phase to the oncoming friction element.
