Fictional 13 and 18 Speed Fuller Transmissions ...

Suitable for ATS and ETS2.
This mod will give you “fictional” 13 & 18 speed transmissions for all default SCS trucks and a few others. There is no real world comparison to gear ratios etc. No effort to achieve technical accuracy was attempted. Top end speed of over 100 mph can be achieved with this mod.
