I have a 95x and it has the 2wd - 4w auto - 4wl configuration. I want to get 4 high. Is there a way i could switch the computers controlling the t-case from a newer X into mine or would i have to get a whole new t-case?????

So far there is no way to get 4 wheel hi. you can get 2 wheel low but not 4 hi.
