i use a center diff with front and rear brakes, my ? is if i lock my tranny in 2nd and still use a servo for brakes will it work properly? im thinking no but could use your help
Yup. First and/or second gear have nothing to do with the gear that drives the center diff (it's a seperate gear). I am using locked 2nd gear with a center diff (although it's a custom one, not the stock one).
To lock the tranny, you can either use the little adaptor by b0gh0s, or you can easily do this mod to do the same thing.
