ABSTRACT:
In an automatic multispeed transmission having at least two centrifugal clutches arranged on a rotary shaft driven by the output shaft of an engine and adapted to engage at predetermined different rotational speeds and higher of the rotary shaft, each clutch having an input member drivingly engageable with an output member by the opening motion of weights, an engagement prohibiting mechanism is provided, which is manually operatable to prohibit the opening motion of the weights of one of the clutches which is engageable at a predetermined rotational speed higher than that of the lowest engaging speed clutch. Further, a disabling mechanism is provided to release the engagement prohibiting mechanism from its prohibiting action to permit the opening motion of the weights when the centrifugal force of the weights is larger than a predetermined value.
