Abstract:
1. A transmission comprising: an input member; an output member; a main shaft operatively connected with said input member; a first and a second shaft member, each spaced from and substantially parallel with said main shaft; a plurality of gears for transferring torque between said main shaft and said first and second shaft members and forming different co-planar, intermeshing gear sets, wherein each of said first and second shaft members has different ones of said plurality of gears concentric therewith and partially forming not more than four of said co-planar, intermeshing gear sets, wherein said co-planar, intermeshing gear sets include: a planetary gear set operatively connected between said input member and said output member; wherein all of said co-planar, intermeshing gear sets are spaced axially between said input member and said planetary gear set; and at least seven torque-transmitting mechanisms selectively engagable to establish at least seven forward speed ratios and at least one reverse speed ratio between said input member and said output member, wherein at least one of said torque-transmitting mechanisms is radially nested in at least a second of said torque-transmitting mechanisms.
