Use GL-4, not GL-5 grade oil.
Owners manual says SAE 90

whats the difference between GL4 and GL5?
GL5 is more slippery, whatever that means. Too slippery for the synchros in the tranny.

Actually the FJ60 Owners manual specs GL-4 or GL-5 in the tranny and t-case. GL-5 is much easier to get and so that's what I run.
I put in Redline MT90. Seems to shift a little easier when it's cold but that could just be wishful thinking. Shifting from second to third seems a little smoother.

Funny-I'm running the MT90 in my H55f. I had run Mobil1 75w-90 previously. I can't detect any difference. I even tried a brief initial fill with conventional Valvoline. Again, no difference. Your probably right about cold weather shifting, it shifts just fine down to the coldest we see here in the area.
