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/<brand.model>/transmission/*.sii and valid unit names end in .transmission.
Attributes
Many common attributes are inherited from accessory_data.
| Name | Type | Default Value | Description |
|---|---|---|---|
| stall_torque_ratio | float | ||
| Torque ratio multiplier if torque converter/multiplier is present. Any positive value is used as multiplier on lower RPM torque. | |||
| differential_ratio | float | 1.0 | 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 | array<float> | This defines the reverse gear ratios in order of decreasing gear reduction. The values should be negative. Example:
ratios_reverse[0]: -11.002 ratios_reverse[1]: -8.875 | |
| ratios_forward | array<float> | This defines the forward gear ratios in order of decreasing gear reduction. The values should be positive. Example:
ratios_forward[0]: 11.32 ratios_forward[1]: 9.132 ratios_forward[2]: 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 1.27.2.1) |
