Default Tranny fluid recommendations

Just picked up a 78 FJ40 (Luke's). I'm base lining the fluids. Seems like there are a lot of opinions on what 90w (GL-4/GL-5/synethetic/dino/ect) to use in the tranny, t-case and diffs. I searched but did not find what I was looking for. Whats the general consenses?

I also discovered my front diff fluid has mixed with the birf grease. Time for a knuckle and wheel bearing rebuild. With only 92k miles, the grease might be original I'll be posting a separate question on that.

Thanks.

Tranny and Transfer I use Redline MT-90. It is a synthetic designed for the older manual trans.
DO NOT use other modern synthetics as they will eat up the bushings in the older units.

I use dino 90wt. I figured that's what was available when mine was built (77), and would be good for replacement...

I generally use what ever Redline product that matches the vehicles needs too when it comes to gear oil.
