Abstract

In a commercial vehicle transmission with a main group and a downstream group including a downstream group countershaft, the downstream group includes means for decoupling the downstream group countershaft in direct through drive so that in direct through-drive the countershaft does not run in an oil sump and no churning losses occur thereby increasing vehicle transmission efficiency.
