I'm using Redline MT-90 for the tranny and LE1605 for the diff.

I'm in sunny San Diego so those mentioned above might be too thick for where you live. Judging by the pics you seem to be where it gets cold.

You don't think that 75w-140 diff fluid is overly heavy for our recommended spec. Sounds like it would do the trick to protect. I used that fluid in the transfer case of my 4wd SUV , but it seems a bit thick for our diff. Just curious.

Any reason for the 75w140 instead of the OEM 75w90 hypoid gear oil?

LE 1605 in the diff and Amsoil 10w30 MTF in the transmission. I'm going to permanantly stay with the LE 1605 but replace the Amsoil with the OEM Honda trans fluid at next change. Nothing wrong with the Amsoil but I really can feel no difference so next time I'll save a few bucks.
