A four-speed transmission having an over drive is disclosed which comprises two basic planetary gearsets and one dual intermeshed planet pinion planetary gearset and three clutches and two brakes. The construction and arrangement is such that an appropriate reduction ratio is provided for each of forward speeds without causing rotary members between input and output shaft to rotate faster than the input and output shafts.
