ABSTRACT:
An adjustable speed automatic transmission includes a variable speed pulley mechanism, a fixed speed ratio drive mechanism and a plurality of clutches in combination. The clutches are selectively engaged to control ouput speed in a low speed range by coupling the variable speed pulley mechanism and the fixed speed ratio drive mehcanism between an input and an output shaft. Alternatively, in a high speed range the clutches are selectively engaged to drive the output shaft directly from the input shaft.
