Actually I drove a 20 speed transmission, for years. It was in a 1967 Crane Carrier concrete mixer, known as the Quad-box or "5x4". It was comprised of a 5-speed main trans mated to 4-speed auxiliary trans. Shifting was accomplished with the use of two separate sticks... every third shift required both hands for a big shift, so you had to momentarily let go of the steering wheel.

It looked like this... (1st gear main & aux is Low Low, skipping gears when unladen.)
Main -Aux
2-2...2-3...2-4...then big shift
3-2...3-3...3-4... then big shift
4-2...4-3...4-4.... then big shift
5-2...5-3...5-4

All this while sitting alongside the diesel engine inches away, no clutching, just rev matching.
