Ton of W Series tranny information.

In my quest for W Series knowlege have come across some interesting stuff!

What about a W59 Tranny?

W59
A common truck transmission, this was the successor to the W56. Like the W56, it came in both 2-wheel and 4-wheel drive versions.

This model appears to have a combination of ratios used in older models of the W-series.

1st and 2nd are low ratios like in the W56 for use to get a heavy vehicle moving.
3rd ratio is the same as in the W57/W58 for a lower rpm drop between 3rd & 4th useful in high-speed acceleration.
4th is direct 1:1 as per design in these boxes.
5th seems to be the base W55 overdrive ratio.
