ok, thanks guys

- GL4 for trans
- GL4 or GL5 for transfer case
- GL5 for diffs and make sure LSD additive for rear

Any recommendations for oil weights for a cold Canadian climate (cold winters, hot summers)...im still thinking 75W140 or might just go with conventional 80W90.


GL4 was a pain to find. Finally asked at NAPA counter and they ordered it in.
