who can help?

I want to make the gearstick moving ...

I added following stuff in engine.jbeam but it does nothing

"props": [
["func", "mesh", "idRef:", "idX:", "idY:", "baseRotation", "rotation", "translation", "min", "max", "offset", "multiplier"]
//automatic transmission
["gear_A", "gearstick", "f7r","f7l","f8r", {"x":85, "y":0, "z":0}, {"x":0, "y":0, "z":0}, {"x":0, "y":0.2, "z":0.01}, 0, 1, 0, 1],
],

I want to make it if you shift up it goes to the dash one time , and if you shift down to the seats like a seqentiel transmission



also some parts like the interior mirror and the seats are from one side visible but from the other side invisible.. How can I change that??
