I use the Amsoil ATF in mine, way quieter in low range and runs much cooler.
(My IR thermometer says about 15 degrees after a long highway run.)

not exact science and such but my Tcase has almost 200K on it and I drove it in 4x4 on pavement a lot.

It probably won't hurt in a pinch, but the 231 t-case is supposed to use ATF.
