I would go even further and note that trucks used to only have 3 or maybe 4 speed transmissions. Rear end ratios meant a lot then, not so much now. It would be interesting to see how 1st and top gear ratios in those old transmissions compared to a modern 10 speed, but I would guess that the modern 10 speed not only has more gears but also a wider range of gears at both ends.
