Im swapping the internals from a cable ys1 into a hydrolic s80 case. Any tricks into doing this a few guys in my area have done it but none tell . I plan on swapping out the diff and all into the hydro case from the cable case. Any help would be greatly appreciated!! oh and neither trans is LSD

 

Heres a guide on doing the reverse. http://www.outlawatvclub.com/users/s...ny_how_to.html guts are basically the same between YS1 cable trannys and hydro trannys, theres not really much to it other than potentially playing with some shims.
