ST205 drain and fill question

This is probably a stupid question but I couldn't find the answer in the ST205 manuals available online as they are not complete, missing the maintenance section.

I noticed the transaxle and the transfer case have their own individual drain plugs, but there is only 1 fill plug on the transaxle side from what I can tell. Do you just add the fluid there and it fills the transfer case for you on its own? Or is there a separate fill for the transfer case that I'm not seeing?

When you fill the transmission through the fill plug in the front it fills the transfer case with oil as well. You are best off draining all of the oil out of both the transfer case and the transmission before refilling. Iirc correctly you will need 5.5 qts of 75w-90 gl5 grade gear oil. The specific instructions should be in the bgb.

Thanks for the confirmation, I figured that's how it had to be I just wanted to make sure I wasn't running around with a dry t-case. I'm probably going to run some syn GL5 80w-90 since it'll be doing drag launches.
