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.
