Let’s only focus on the reverse gear position, I believe there are as follow:
-
all the way to the right and down.
-
all the way to the right and up.
-
all the way to the left and up.
-
knob pull then shift to left and up.
For me, if I drive an old 5 speed then 1).
For modern cars with 6 speed, I prefer 4). It makes me feel confident that I am definitely in reverse.
A 6 speed with 3) imo is just terrible. I know many BMWs have this pattern. The idea is to really push to the left so you engage reverse and not 1st. Tried it on a friend’s car and I was quite nervous: what happen if I yank too hard and damage the shifter?
The unnamed International transmission in my dad’s old dump truck has reverse completely to the left and down. Conveniently placing it right in the middle of your goddamn leg.
It might not have been located quite that far over when new but now you basically have to scooch over and hug the driver door whenever you’re backing up at all.
Honorable mention to the 6sp ZF trans in my dad’s F550 flatbed, where reverse is left-and-up, also putting it near your knees and also in nice range of the hanging keys out of the ignition to whack against it randomly.
