Summary
The cvt gearbox shift logic controller handles the gear ratio selection of the transmission and torque converter lockup.
It is an extension of the vehicle controller
and automatically gets called if a vehicle is equipped with an CVT transmission
.

JBeam Properties
A lower number increases smoothness but delays response to vehicle speed.
A lower number increases smoothness but delays response to vehicle speed.
Higher number causes faster downshifting decision when throttle is applied
Higher number causes faster upshifting decision when throttle is applied
CVT transmissions only support P, R, N and D modes.
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.
Smaller numbers means the transmission will adjust it’s ratios more slowly.
The cvt will try to vary its ratio to achieve this engine speed when accelerating at full throttle.
The low load engine RPM target for the engine with cvt gearbox.
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.

Current gear the transmission is in.
Current position of the automatic shifter.
Sends torque and power related data to the UI.
Public Properties
