I’ve got a quick question for you all. I’ve searched about this but didn’t find anything conclusive. I’m about to do the t-case fluid on my evo (06), and am wondering if what you're supposed to do is just top off the tcase through the acd reservoir in the engine bay after you’ve drained it? Thanks in advance.

Damian.

 

No!!

You fill it up thru the hole on the side of the diff. It's on the passenger side. fill it until the fluid start overflow thru the same hole.
