645:) have dog-leg five- or six-speed transmissions, because second gear is fine for normal starting; first is considered a "crawler" or "granny" gear in these trucks and is only used for starting with heavy loads and/or a trailer, or descending steep grades. In many older trucks, the shifter is marked with "Low" instead of "1", and 2nd gear is marked as 1st instead. A 4-speed truck gearshift might read "R, Low, 1, 2, 3", rather than "R, 1, 2, 3, 4", since the transmission is considered a 3-speed with an auxiliary low gear rather than a normal 4 speed.

Dog-leg layout gearboxes were a reinterpretation of the classic 5-speed gate pattern: as in road racing more frequent shifting occurs from second to third than from first to second gear, the dog-leg gearbox puts 2nd and 3rd gear opposed one to the other, for a very quick up-shifting or down-shifting.

shift pattern distinguished by an up-over-up shift between first and second gear. The layout derives its name from a dog's hind leg, with its sharp angles. Dog leg gearboxes were replaced in most mass production vehicles by transmissions with a standard gear layout. Most modern manual performance

The dog leg gearbox is typical of nine- and ten-speed heavy-truck transmissions. In the case of a ten-speed transmission, the gears are 1–5 in the low range and 6–10 in the high range (the 1 position is not used in the high range of a nine-speed transmission).

This could bring the driver a great speed range with only one shift, which was particularly suitable for hillclimbing. They were transferred to sports cars in the 60s as a desirable feature. With the introduction of 6-speed manual gearboxes in the mid-90s and
