Summary
The automatic gearbox shift logic controller handles the automatic shifting logic of the transmission, the different drive modes and torque converter lockup.
It is an extension of the vehicle controller
and automatically gets called if a vehicle is equipped with an automatic transmission
.

JBeam Properties
A transmission with only manual modes will not shift automatically while in realistic shifting mode.
This can be used to simulate automatic transmissions with manual valving, as found on some racing vehicles.
This is based on the RPM of the converter output, so it will occur at the same speed even if the converter is heavily slipping.
Set 0 to automatically calculate.
Will not occur in sport/manual mode. Set 1 to disable for older style mechanical gearboxes
Electrics
Indicates the position of the torque converter lockup clutch. 0 means it’s disengaged, while 1 means it’s fully locked.
Public Functions
Switches between arcade and realistic gearbox modes.
Switches to the next position on the gear lever.
Switches to the previous position on the gear lever.
Shifts the gear lever to the selected position.
Current gear the transmission is in.
Current position of the automatic shifter.
Changes the gearbox’s default forward mode.
Sends torque and power related data to the UI.
Public Properties
Indicates if the engine is disabled.
Indicates clutch input. 1 is fully engaged, 0 is fully disengaged.
