MSTUS uses 4 engaging and disengaging operations using dog clutches to achieve smooth uninterrupted shifting :
All engagement and disengagement operations occur via dog clutches while the RPM of the gears and their respective shafts are synchronized, requiring minimal force to engage/disengage. A graphical representation of the above steps for up-shift from ratio A to B and down-shift from ratio B to A is shown in the figures below.
