When upshifting, a "coasting" throttle is applied. Hill hold is also implemented via brake when rolling backward.

When the vehicle is stopped, transmission is in gear and brake is released, the clutch is engaged a little bit to make the vehicle creep forward without throttle, just like a conventional slushbox. A custom throttle logic is added to control the rev-match during the shift, and the clutch engagement RPM is based on the "Throttle-Based Torque Converter Lockup Logic"(my previous mod), Clutch spring is also tuned to make a manual/sequential " backlash" feeling. The torque converter is converted to an empty box w/ a clutch, the clutch is fully disengaged while shifting, decoupling the engine and the gearbox. The SCT is actually a "workaround" of the current AT physic/logic.
