ManualGearbox

The manual gear box (device name "manualGearbox") is a model of an manual transmission. In a Powertrain, it can be placed behind a viscousClutch or frictionClutch, and should have a shaft, differential, or splitShaft connected to it. It can have any number of gears. The manualGearbox accumulates damage on each gear from shifting while the gearbox is still transmitting torque. When the damage reaches 100%, that gear will fail (act the same as neutral).

Jbeam Properties

Name	Type	Optional	Default Value	Description
gearRatios	array	false	na	This array is the list of gear ratios available to the gearbox. 0 represents neutral. A negative number indicates a reverse gear. The gearbox will have as many gears as specified in the array. Ex "gearRatios":[-3,-2,0,4,3,2,1,0.5] has 5 forward and 2 reverse gear ratios.
gearDamageTreshold	number	true	3000	Maximum damage accumulation before a gear breaks. Damage is accumulated per gear.
friction	number	true	0	The friction torque applied to the input side of the gearbox.
