Good morning, I have a hard idea but possible to do because scs software did it: while driving Gavril T-series with manual gearbox, when player is driving on the last shifter's gear, and when the player wants to switch to the next vehicle's gear, he won't use keyboard, but he will move the shifter's lever to the 1st gear's placement, when player is switching to the next vehicle's gear, player will move shifter's lever to the 2nd gear's placement ect. This idea isn't only for Gavril T-series but even for more vehicles with more gears than the count of shifter's gears. I believe in you.
