Documentation/Engine/Units/accessory transmission data
The accessory_transmission_data unit class is used to define the transmission characteristics for the player's vehicle, as well as the differential ratio. Units of this type are usually defined in /def/vehicle/truck/<make.model>/transmission/*.sii and valid unit names end in
Many common attributes are inherited from accessory_data.
|stall_torque_ratio||float||This defines the maximum torque multiplication of the torque converter for an automatic transmission. The torque output of the transmission is clamped to a maximum of (engine torque × gear ratio × stall_torque_ratio). That is, the output torque stops increasing once the output speed drops below (engine speed ÷ gear ratio ÷ stall_torque_ratio). If unset, the transmission behaves like a conventional transmission without a torque converter.|
|differential_ratio||float||This defines the differential/final drive ratio between the transmission output shaft and the wheels.|
|retarder||uint||0||The number of output levels for the retarder if applicable. If zero, retarder behavior is disabled for the transmission.|
|ratios_reverse||float_array||This defines the reverse gear ratios in order of decreasing gear reduction. The values should be negative. Example:
ratios_reverse: -11.002 ratios_reverse: -8.875
|ratios_forward||float_array||This defines the forward gear ratios in order of decreasing gear reduction. The values should be positive. Example:
ratios_forward: 11.32 ratios_forward: 9.132 ratios_forward: 7.207 ...etc...
|transmission_names||owner_ptr||Points to a unit of the type transmission_names, usually nameless and within the same unit definition file or included from a Serialized Unit Include (.sui) type file. This is used to assign custom names to each gear in automatic and sequential modes (these are overridden by h-shifter pattern definitions).|
|crawls||uint||0||The number of ratios_forward to handle as crawler gears for UI display. (Added in ETS2 188.8.131.52)|
