4 speed automatic transmission

This is my attempt at making a functional automatic transmission and it works pretty good. Its a sliding mesh gearbox with centrifugal clutch controlling the selected gear according to output shaft speed. With current settings, it needs a motor that spins at 2000 rpm If it doesn't work in your vehicle try increasing the peak torque of centrifugal clutch. If it works but only in reverse, change motor spinning direction and invert centrigual clutch pulley belt direction :) green=input side red=output side
