Hi,
The answer would also be 'no' if you're referring to automotive automatic transmission fluid.
The current name for JD hydraulic fluid is Hy-Gard, and that's what you want in the differential-style direction reverser. Plus, it's also what you want in the lift hydraulic system.

I never thought of ATF, I was just thinking of gear lube. According to the sevice manual, you can use Type A automatic trans fluid. Type A is not longer around, but I believe that Type F is the replacement. I still would not use ATF, I am just not a fan of it.
As far as Hy-Gard in the hydraulic system, you will get some pressure loss, and some increases howling. For whatever reason, these old gear pumps do not seem to like Hy-Gard and will howl. If/when I run a multi-trans, I always have to reshim the bypass to get pressure back. If cross contanination with other later model machines is not an issue, I have better luck in the hydraulics with a straight weight hydraulic oil. I normally run an AW68, if you are in real cold conditions, you could drop a wieght.
