The principles of the boxes are very similar although in some applications you might find the gear engagement done by compressed air rather than mechanical linkage from the pedal. The fluid flywheel should be kept in mind all the time, do not set off in too high a gear, nor engage a higher gear too early. Do not let the engine labour in too high a gear.
As for the box, do not skip gears, neither up nor down, go through the box in sequence, if not, bands will suffer, or worse.
