Well, I use ATF as well. Any concerns what negative effect engine oil or in fact ATF might possibly have on O-rings?
Auto transmissions are full of O ring seals and they get on just fine. Transmissions run a lot hotter than chains, too.
There have been auto trans that ran engine oil, such as the original BMC Mini Auto frinstance, (not the VW based things) and they worked ok too.
