A method to control the execution of a shift to a higher gear with a released accelerator pedal in a drivetrain provided with a dual-clutch, servo-assisted transmission, comprising the steps of: opening, in a first instant, an outgoing clutch; closing, in the first instant, an incoming clutch; synchronizing, between a second instant and a third instant, a rotation speed of the internal combustion engine with a rotation speed of the incoming clutch, namely with the rotation speed imposed by the gear ratio of the following gear; completely opening, in the third instant, the outgoing clutch; completely closing, in the third instant, the incoming clutch; keeping the torque transmitted by the outgoing clutch constant between the second instant and a fourth instant; and keeping the torque transmitted by the incoming clutch constant between the second instant and the fourth instant.
