Claim:
A power shift parallel shift transmission comprising: a plurality of parallel torque-transmission branches, each of which is formed on an input side by one of a plurality of intermediate elements ( 3 , 4 ) each of which is connectable, by an associated power shift element (K 1 , K 2 ), to a common input element ( 2 ) and, on an output side, by one of a plurality of drive output elements ( 5 , 6 ) each of which is connectable to an appropriate one of the plurality of intermediate elements ( 3 , 4 ) by a transmission ratio step (A 1 -A 4 ) engaged by a respective clutch (S 1 -S 4 ), and the plurality of drive output elements ( 5 , 6 ) comprising at least first and second drive output elements ( 5 and 6 ); at least the first and the second drive output elements ( 5 , 6 ) having a driving connection to a common output element ( 7 ) such that the transmission ratio steps (A 1 -A 4 ) are distributed in alternation, in the sequence of their transmission ratios (i A1 -i A4 ), across the plurality of intermediate elements ( 3 , 4 ) and in groups of adjacent transmission ratios (i A1 , i A2 , i A3 , i A4 ) across the first and the second drive output elements ( 5 , 6 ); and at least one of the first and the second drive output elements ( 5 , 6 ) being in drivingly connected with the common output element ( 7 ) via at least a first two alternatively shiftable output transmission ratio steps (B 1 . 1 , B 1 . 2 ; B 2 . 1 , B 2 . 2 ) that have different transmission ratios (i B1.1 , i B1.2 ; i B2.1 , i B2.2 ).
