<p>A transmission has a first and a second planetary gear set with four input torque-transmitting mechanisms, such as friction clutches, to achieve torque flow through the planetary gear sets to a countershaft gearing arrangement. The transmission includes an input member, an output member, a pair of planetary gear sets, an input clutch assembly having four input clutches and a countershaft gearing arrangement. The countershaft gearing arrangement is operatively connected with the planetary gear sets and includes: three co-planar intermeshing gear sets, first and second countershafts, a first intermediate shaft, a second intermediate and a third intermediate shaft concentric with the input shaft.</p> |
