A vehicle includes an engine and transmission having gear sets, an input member that is continuously connected to the engine and a gear set, a binary clutch assembly, a speed sensor, and a controller. The binary clutch assembly includes a freewheeling element holding torque in one rotational direction, and also a selectable one-way clutch (SOWC) portion holding torque in two rotational directions when applied. The controller executes a method to transmit a first binary clutch command to the binary clutch assembly and thus apply the SOWC portion at vehicle launch, and calculates, via the processor, an acceleration value of the vehicle using the measured speed. The controller also selects a shift apply point of the binary clutch assembly as a function of the calculated acceleration value, and transmits a second binary clutch command to the binary clutch assembly to release the SOWC portion at the selected shift apply point.
