Realistic Engines for Peterbilt 579, Kenworth T680 and W900

With the release of the W900, I’ve decided to update my Realistic Engines and Transmissions pack for ATS.
Version 2 Changes: -edited stock engines to comply with my pack -removed my engines that were duplicates of stock -created 6 Allison 10 speed “automatics” (they feel pretty good!) -added all of KW_Drivers EF transmissions to the W900
