I noticed that now the reverse works like the low in the fine tune gearbox allowing you to regulate how much throttle you want. Maybe since the addition of the finetune they mess up something in the other gearboxes and now the reverse act like finetune in all the gearboxes.
Indeed, in balanced, off-road and probably high-range (cant test because I cannot load my main save) the shifting to reverse behaves like in the fine-tune gearbox but without the throttle regulation and its not possible to stay in the middle of that slider.
Since they added the small scales to the low gears, shouldn't they be visible on reverse also? Something like this maybe.
