A transmission selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes an input shaft, a mainshaft, an output shaft, a first countershaft and a second countershaft. A first gear set includes a first mainshaft gear arranged on the mainshaft, a first countershaft gear arranged on the first countershaft and a first countershaft gear arranged on the second countershaft. A second gear set includes a second mainshaft gear arranged on the mainshaft, a first countershaft gear arranged on the second countershaft and a second countershaft gear arranged on the second countershaft. The gears of the first gear set all have a first helix angle. The gears of the second gear set all have a second helix angle. The first and second helix angles are selected to provide gear constant leading whereby thrust forces directed onto the first and second countershafts are balanced.
