Abstract
A shifting element system for a transmission comprising at least one first shifting element () and one free wheel () wherein one input element of the free wheel () is mechanically coupled with one input element of the first shifting element () and wherein one output element of the free wheel () is non-torsionally connected with one output element of the first shifting element (). It is proposed that input and output elements of the first shifting element (), discs () of the first shifting element (), a free wheel () and input and output elements of the free wheel () form a pre-assemblable unit wherein a free-wheel sprag unit () of the free wheel () has one bending elastic holding device () by which the input element of the free wheel (), during and after assembly of the pre-assembled unit, is axially movably secured opposite the output element of the first shifting element ().
