Transmission fluid has been around for a very long time - nothing new or different about it at all. For cleaning about any oil with a solvent will clean dried up oil - it is how much damage it does to the paint. I try to go conservative on that. For oiling a thin oil will work. BTW I did some research a while back with a man who ran an oil lab. You can use your transmission fluid - but I don't know why you think you need to make such a big deal about it.
