Hi guys, I report you my today`s job.
I changed differential oil last week. Then I changed transmission oil today.
At first I had to remove under floor panel. Driver`s side bolts is OK but passenger side bolts was not able to remove alone.



Remove front muffler pipe from catalyst converter.


Remove drain bolt. I hear like a brow off air sound from transmission drain hole.

I guess that inside of atmospheric transmission case are different atmospheric.

???????????



Some guy knows about me, I living in Japan. I ordered this one for GM parts dealer in US. But this gasket was made in Japan. So ridiculous story I imported this parts from US, but this parts export to US from Japan.
I know AR5 export form Japan made by Aishin. It`s cannot be help.

Re-fill plug position was narrow space there. I used plastic pipe.
Then re-fill from engine room.



I found many metal powder in the pan. I decide change oil every 20000 mile.

Sorry LLLFEY, I never checked drain plug size. and if I miss understand your mean, sorry. Your comment "magnet plug" was differential magnet plug is not it?
If it so, I am not sure it was not different size AR5 drain plug and differential plug.

I sent you my message to your private box. Sorry if you mean (rear) was Diff, 28oz is
Normal, but AR5 oil capacity is bigger than diff.
I am not sure when I drain AR5 oil, the quantity of the drain oil was the approximately 77~79oz.
Mine needs oil when re-fill to unit, Diff=over 40oz + LSD lub, AR5=approximately 94oz.

It was my case, I keep body horizontal when drain oil and re-fill.
If your car body was not able to keep horizontal position, oil was not perfect drain.
As a same time, you could not re-fill the oil correctly.
