all automatics use some sort of manual override of the transmission, with numbered positions in descending order marked below (or to the right) of "drive", which will prevent the transmission shifting to a gear higher than the selected, but maintaining automatic operation between all lesser numbered gears. such gates will appear as "p-r-n-d-3-2-1" for example. on some vehicles (mainly japanese makes such as honda, toyota and lexus being good examples) these numbered positions are replaced by a single "l" (for "low") position, which will hold the transmission in whatever lower ratio is required for climbing steep grades or for heavy acceleration. so, it is p-r-n-d-3-2-l
