An automatic speed change apparatus including an input shaft, an intermediate
shaft and an output shaft arranged in parallel. The input shaft is coupled to the
intermediate shaft by counter gear sets providing first, second and third drive
paths. The input shaft is provided with clutches for engaging or disengaging the
second and third drive paths and with a brake. The intermediate shaft is provided
with a clutch, a brake and a one-way clutch for engaging, disengaging or braking
the first and third drive path and with planetary gear sets. The first drive path
is coupled to a ring gear, the second drive path is coupled to sun gears, and the
third drive path is coupled to a planetary carrier. A planetary carrier and a ring
gear are connected to the intermediate shaft, and the intermediate shaft is coupled
to the output shaft by a fourth counter gear set.
