Abstract
A transmission system has a main transmission, a sub-transmission, and a transfer clutch for four-wheel drive. The sub-transmission has a reduction gear train for providing a low speed range. A gearshift lever of the main transmission has an ultra-low speed position in a shift pattern. When the gearshift lever is shifted to the ultra-low speed position, a first speed gear of the main transmission and the low speed range of the sub-transmission are selected in response to the operation of the gearshift lever. Further the transfer clutch is engaged, so that ultra-low speed by the four-wheel drive is provided.
