A transmission is provided that utilizes three planetary gear sets and three layshaft gear sets, as well as four rotating-type clutches and one brake that are engagable in different combinations to provide eight forward speed ratios between an input member and an output member of the transmission. By combining features of a layshaft transmission with those of a planetary transmission, the low spin losses and packaging convenience typical of a layshaft transmission are available while still achieving the high torque capacity typical of a planetary transmission. |
