A transmission includes an output shaft, a first gear rotatably mounted on the output shaft, a shuttle movably axially on the output shaft, and an engagement member fixedly mounted on the output shaft. The first gear includes first dog teeth. The shuttle includes second dog teeth which engage the first dog teeth. In a drive condition, the engagement member axially moves the shuttle into engagement with the first gear, first surfaces of the first and second dog teeth engage, and, as a result, the first gear rotates in together with the output shaft. In a freewheeling condition the output shaft is stationary, an overdrive of the first gear results in engagement of second surfaces of the first and second dog teeth, and, as a result, the shuttle moves out of engagement with the first gear allowing for free rotation of the first gear about the output shaft.
