Has anyone used Amsoil ATF in the hydraulic system? not sure what came out of my system that I drained.
Thanks

I personally wouldn't refill a system with ATF. I would look for a quality hydraulic oil such as Chevron 5606A. Its very similar to ATF in fluidness and its also red in color, but it doesn't have a bunch of the additives that ATF does. When in a pinch ATF would be fine, however ATF has a tendency to deteriorate rubber lines pretty fast causing more issues down the line.
Just my thoughts on it, from my experiences.

Carl, do you have an idea of mixing the existing atf in a system with hydraulic oil? Just curious.

From my previous experience with auto transport, a lot of people in the 48 states "cut" their AW-32 with a few quarts of ATF.
From my personal experiences, with older equipment and rubber lined hoses, I've had hoses delaminate and cause problems. Some of the newer high pressure low weight hose solutions are really nice using "Pex-like" liner tubing with high strength nylon wrapping and a lightweight protective outer jacket. Being in Alaska limits me to what's available, using a product like Chevron 5606A was our best option. Cold will find a weak spot and tear things up. The Chevron 5606a has a working temp of -66F to +266F, I once split the Aluminum of a 2 stage cylinder by pushing to hard at -68F. The next day I had a chat with the boss and informed him that while our equipment might be rated to work in those temps... I am not!
The main benefit of using a better fluid is the ability to use it in colder temps, while lowering the strain on the moving components. Such as the pump or cylinders themselves.
While I know that the average Newell/RV user isn't going out in -20 weather, I wouldn't hesitate to.
