ABSTRACT:
A transmission comprises gear trains which provide increasing speed ratios and two clutches which are operable independently to provide alternative paths through the gear trains between an input and an output. The gear trains provide alternate ratios driven respectively through one and the other clutch. The input comprises a first shaft drivable by one clutch and a shaft drivable by the other clutch. A layshaft is provided through which drive in a selected ratio is transmitted from one of the first and second shafts to the other to drive the output which is also a shaft. One of the first and second shafts has a gear thereon which meshes with a gear on the output shaft.
