As in tractor hydraulic oil?
I believe it's a ~20wt based oil, so it would probably work, but for how long I dunno. It probably doesn't have the proper additives for an auto trans.

Ok, you could probably get away with it in your PS like you asked about in your other thread. In a transmission? Don't even think about it. (Unless of course you enjoy replacing transmissions)

Awe c'mon KD0, it's for the sake of science!
In an emergency to get you to a place where you can get some proper ATF that has the correct friction characteristics, sure. Or if you just want to experiment with it in an automatic transmission before you haul it to the crusher, sure.

Well in that case, go for it!

I am really surprized by this question with all of the available technical information on this website.
I would strongly recommend against using it unless you simply want to do an expensive experiment.
Hygard and Dexron ATF's are totally different formulations.

Are you wanting to use that Hy-gard only because you already have some, or because you can get a good deal on it, or what?
Deere does have some EXCELLENT tranny fluid that would work perfectly in any GM 4L series tranny (4L60, 4L60E, 4L80, 4L80E, etc, etc). It's called "HD SynTran " and carries Allison license AN-071006. It's a VERY robust version of what would be considered DEX-III/Mercon type fluids. And it's stupid expensive. And it's overkill for just about anything you'd need.
It would be my suggestion that you simply go out and get any brand name or house brand Dex/Merc fluid from a credible source (Mobil, Castrol, Valvoline, ST, AAP, AZ, etc).

Hygard is way too thick for an auto trans, and that's viscosity alone. There is a low viscosity Hygard, but even it is probably too thick, not to mention different additives.
Leave the Hygard in the tractor.

It seems many of his posts are asking about using some sort of JD fluid in an application is wasn't designed for. IIRC from one of his previous threads, he can get them cheap through his employer.

Yes, too thick (9.4 cst @ 100, about a 30 grade) plus it's formulation and additive package is more suited to a differential than an automatic trans. I wouldn't be afraid to use it in a part-time, chain-drive transfer case (I have use THF products like that before). Maybe even a manual trans subject to a lot of study. Automatic, no way, Jose!
Power steering, as on your other post. Maybe. The additive package might work but the viscosity is off.

If you're serious about using Hygard, at least use the low-vis.
We've been using the low-vis for about 20 years in various power steering pumps after a Deere rep told us if we wanted to permenately fix the Dodge's leaky pump seals. It worked and we never had to replace that pump.
I use HyGard/HyGard Low-Vis in numerous hydraulic systems, its a great fluid, even in the transfer case on my Ford Super Duty.
I've read that the guys who go to the drag strip have found out that HyGard is the only fluid that they will use in their automatic transmissions. I have no first-hand knowledge on this, its what I have read.
I know this is the transmission question post, but I wouldn't hesitate using it in a power steering system, its far superior to its ATF counterpart in any hydraulic system.
As far as your transmission is concerned I would absolutely do more research, although I really don't see there being an issue as you can always add the proper Lube Guard product if needed.

Here are two undisputable facts:
1) a decent house brand DEX/Merc fluid is essentially very cheap by the gallon, and is perfectly suited for this application; VOAs and UOAs show these are great options
2) nothing from the House-o-Green is cheap; Deere does have great fluids, but they are application specific and usually pricey
Even with some kind of discount, I doubt he'd be able to get below costs of normal ATF from Walmart, and with no assurance that the Hygard would work well, why risk it?

Hey guys havnt been on here for a day or so. I was never going to use hygard in my truck. I was just wondering if you could. I will however try it in my power steering. I use castrol dexIII in my 4l60e. It loves it!
