ABSTRACT:
In an an automatic transmission, a low and reverse brake is arranged radially outward of a high clutch. The gripping plates of the low and reverse brake are arranged axially offset from the high clutch such that a diameter of the transmission is kept small. A piston of the low and reverse brake is associated with the gripping plates by way of arm members having cutout portions therein to allow a sensor, which penetrates the transmission casing in the vicinity of the low and reverse brake, access to a clutch drum of the high clutch so as to sense a rotation speed on an input shaft to which the high clutch is connected.
