There is also a transfer case next to the transmission that needs periodic fluid changes with 80W-90 gear oil.

yep, gonna do that as well. I have an 09' Acura Tl SH-AWD. i always do the transfer case with the rear diff fluid change on my car. I'm just shocked she allegedly never changed either rear diff or transfer case.

Thanks guys for the replies! I'll definitely post a few pics of how dirty the oil is. I'm also doing her timing belt, water pump, spark plugs, valve adjustment and A/C compressor since its making a noise. TB/WP HAS NEVER BEEN CHANGED EITHER! I told her she's lucky the timing belt hasn't snapped. These are interference engines so it would've definitely bent a few valves if the belt broke.
