摘要： A transmission for a vehicle is configured to provide nine forward gears in sequence from the first gear to the ninth gear The transmission includes
a first and a second planetary gear set, wherein
the first and second planetary gear sets are configured axially in series, wherein
each planetary gear set is configured to provide a first and a second forward speed reduction and one direct speed with a one to one (1:1) speed ratio, the first forward speed reduction being larger than the second forward speed reduction, thereby providing three forward speeds with different speed ratios wherein
each planetary gear set is configured to be individually shiftable between its three forward speeds
wherein the transmission is configured to provide
the first to third gears by utilizing the first forward speed reduction of the second planetary gear set and by alternating the three forward speeds with different speed ratios of the first planetary gear set,
the fourth to fifth gears by utilizing the first forward speed reduction of the first planetary gear set,
