A multi-speed transmission with an input shaft ( 1 ) and an output shaft ( 2 ) with two spur gear speeds (ST 1 , ST 2 ) that are connected tightly on the input side with the input shaft ( 1 ) and generate two output rotational speeds (n 1 , n 2 ), with a main gearset that is connected with the output shaft ( 2 ) and is constructed as a two webbed four shaft transmission with two coupled, shiftable planetary gearsets (RS 1 , RS 2 ) to which the output rotational speeds (n 1 , n 2 ) of the spur gear speeds (ST 1 , ST 2 ) are transferable through several shifting elements (A to E) through their selective closing to the clutch of at least six forward gears and can be shifted without group shifting. A total of six shifting elements (A to F) are provided. The output rotational speed (n 1 ) of the first spur gear speed (ST 1 ) is transferable through the sixth shifting element (F) to the second shaft of the main gearset, and at least eight forward gears and maximally two reverse gears are shiftable.
