How to fill transmission chain link
1985 4Runner A340H automatic transmission
I am in the midst of changing out the filter and fluid in my 85 4Runner and thought it wise to also drain this little pan between the Transmission and transfer. I understand this is the chain link? I pulled the drain plug and about 1 quart of ATF drained but I don't see a fill plug for this. Do I fill this through the transfer case or when I fill up the transmission, will it fill this too?
Thanks,
JARED

Just as an edit, I found a nice image of an A340H transmission including transfer case and it does look like the chain drive section gets refilled from the transmission (indicated as a red arrow showing the passage between the transmission and Chain Drive compartment). Can anyone confirm this?

Thanks MechKW. In total (not including the transfer case which I didn't drain), 9 quarts of ATF came out: 7 in the transmission and 2 in the Chain Drive link. When I fill it back up, I'll fill 7 quarts, start the Runner in Park then add the final 2 quarts.
