This mod adds more differential for original SCS transmissions in ATS. Differential ratio is a number which means how many times slower the axle rotates than the cardan shaft. The more differential ratio is - the slower your truck goes at the same RPM. I made bigger differential ratios for more realistic driving and better handling of heavy cargoes. The last differential, 4.11, should be enough for carrying ~100 ton trailers. The mod: - does not replace anything, works as addon - does not change gear names - adds 3.25, 3.55, 3.73, 3.91 and 4.11 differentials for all vanilla transmissions - has real differential ratio numbers - works not only with Eaton 13 and 18 speeders, but with every transmission in the game including 10 speeders, Allison and 12 speeders - has default prices and unlocks for all transmissions - works with any version of the game - works with any priority in mod manager
