The invention relates to the vehicle technology, and discloses a transmission which comprises a transmission box body, a first shaft, a second shaft, a parking gear and a synchronizer. The first shaftand the second shaft are provided with a first transmission mechanism and a second transmission mechanism which are used for power transmission between the first shaft and the second shaft, and a first clutch is arranged between the first transmission mechanism and the first shaft so as to control transmission connection or disconnection of the first transmission mechanism and the first shaft. Asecond clutch is arranged between the second transmission mechanism and the first shaft so as to control transmission connection or disconnection of the second transmission mechanism and the first shaft. The parking gear and the synchronizer are arranged on the first shaft, the parking gear is connected with the transmission box body, and the synchronizer is located between the parking gear and the first transmission mechanism. In addition, the invention further discloses a two-gear coaxial axle assembly comprising a gearbox, and a vehicle comprising the two-gear coaxial axle assembly. According to the transmission, unpowered interruption gear shifting can be achieved, meanwhile, parking braking can be achieved, and the safety performance of the whole vehicle is improved.
