Totally forgot that I never replied to this, and surprised that 7 months later here I am about to do the same thing (fluid change) hahaha. Transfer case I am good, I have a quart of Diaqueen in my garage already. Now do I need to buy another quart for the rear diff, and a bottle of ATF for the other "side" of the rear diff that the AYC/ACD 'sits' in? I think that's my question, and honestly I cannot remember what I did the first time I had to do this. Sorry for my stupidity.

All in all, I have (1) bottle of Diaqueen. I should need 1 more, and then 1 bottle of ATF correct?

Thanks.

 

same oil for the front and rear diff. Diaqueen gear oil. so yup. 1 more quart for rear diff and ATF for the ayc/acd

 

Forgive me if I'm wrong, but isn't the "front diff" considered the tranny? Haha. Sweet, thanks!

 

The front diff of an Evo X is in the transfer case, so deanob was correct.
