2 layshafts by the looks of it? taken from the site:

"The dual layshafts each have their own unique final drive ratio. One layshaft - with a final drive ratio of 2.88:1 to the differential - contains first, second, fifth and sixth gears. The second layshaft - final drive ratio 4.25:1 - contains third, fourth and reverse gears"

Why do I have to have the difficult box
