Abstract
The present invention provides a 24 forward speed, 12 reverse speed transmission for use in a work vehicle, e.g., an agricultural or industrial tractor. The transmission uses 10 clutches, with six arranged in a speed section and four in a range section. The speed section arrangement can provide six forward and three reverse speeds, while the range section can provide four ranges. Optionally, the transmission may be provided with a selectively engageable power take-off shaft and a selectively engageable front wheel drive take-off. The entire structure provides a very small speed change requirement between the diffrent gear ratios.
