Abstract
Provided is a wheel loader in which the speed position of the transmission can be easily changed with a small number of switches. The wheel loaderincludes a tilting angle sensorfor detecting the tilting angle of the vehicle body. In case that the vehicle body is traveling on an uphill or a downhill with a transmissionin a higher speed position than the lowest speed position, and the tilting angle detected by the tilting angle sensoris not smaller than a prescribed threshold value, a transmission control devicesends the transmissiona command to downshift the transmissionone speed position by each operation of a shiftdown switch
