2 speed Automatic transmission

An actual self shifting 2 speed transmission. First gear is 3:1 and second gear is 1:1 i did a 3 speed version of this but i didnt se any reasons for it as we dont have high reving engines. so a 2 speed automatic will do perfect for the engines we have in game. if you think it shifts too early just decrease the spring rate. and if it shifts to late increase the spring rate. i hope this transmission will help you in your creations. and yes modifications are allowed. (Shifts by tourqe and not by output RPM)
