A third option, layshaft with winding path, is a particular case of a layshaft transmission design that achieves unique gear ratios through multiple meshes of parallel axis gears, sometimes incorporating multiple countershafts. Such an architecture can increase the availability of fixed gear ratios while reducing the number of rows of gear pairs, but at the sacrifice of mesh efficiency.
