Climb up into an older 40 ton truck and you will see why they are now automatic.there's 7 gears now... a lot different to the 3 in the past...

On the gear stick is a smaller lever, this is to change gear ratios, not actual gears. There are two sets of gears, high and low ratios. You change from one to the other with the help of the clutch pedal.

In all there are sixteen forward gears, but you don't need to use them all, for the most time the driver will be in 16H or sixteen high ratio.
No wonder automatic is much more preferable, and these days the onboard computer can sense downhill movement and assist with controlled braking by lowering the gears.
