I have a 2006 RUBICON . I also like the "auto" feature ,when you want it .You can put it in any gear you want, at any speed in esp . No computer "override" .Keeps the RPMs down and keeps my HMF pipe quiet . I dont think there are any actual "gears" its all hydraulic . ESP only simulates different gears.The Trans doesnt seem to make alot of noise. The LOW gear is alot of FUN . It only does @ 38mph in low before it bounces of the rev limiter . If you use low and ESP its really responsive keeps the rpms right were you want them .Great for hill climbing or mud .The price is a little on the high side , but if you keep looking around sometimes you see them for @ $6000. GOOD LUCK ,HOPE THIS HELPS !
