a first clutch directly connected to the second primary shaft and drivingly connected to the input shaft; a second clutch directly connected to the first primary shaft and drivingly connected to the input shaft; a first countershaft having a plurality of even gears (114a, 114b) selectively fixed thereto, a plurality of odd gears (114c, 114d) selectively fixed thereto, a first rigidly fixed gear attached thereto, and a second rigidly fixed gear attached thereto, wherein each of the plurality of even gears (114a, 114d) is selectively in driving engagement with a different one of the plurality of gears (106a, 106b) rigidly fixed on the first primary shaft, each of the plurality of odd gears (114c, 114d) is selectively in driving engagement with a different one of the plurality of gears (108a, 108b) rigidly fixed on the second primary shaft, and the first rigidly fixed gear attached to the first countershaft is in driving engagement with the output shaft; a second countershaft having a plurality of even gears (116a, 116b) selectively fixed thereto, a plurality of odd gears (116c, 116d) selectively fixed thereto, and a first rigidly fixed gear attached thereto, wherein each of the plurality of even gears (116a, 116b) is selectively in driving engagement with a different one of the plurality of gears (106a, 106b) rigidly fixed on the first primary shaft, each of the plurality of odd gears (116c, 116d) is selectively in driving engagement with a different one of the plurality of gears (108a, 108b) rigidly fixed on the second primary shaft, and the first rigidly fixed gear attached to the second countershaft is in driving engagement with the output shaft; characterized by a reverse countershaft having a plurality of odd gears (118b, 118c) selectively fixed thereto and one or more even gears selectively fixed thereto and a rigidly fixed gear attached thereto and drivingly engaged with the second rigidly fixed gear attached to the first countershaft, wherein each of the odd gears (118b, 118c) selectively fixed to the reverse countershaft is selectively drivingly engaged with a different one of the plurality of gears (106a, 106b) rigidly fixed on the first primary shaft and the one or more of the even gears selectively fixed to the reverse countershaft are selectively drivingly engaged with a different one of the plurality of gears rigidly fixed on the second primary shaft. an input shaft drivingly connected to an engine;
