installing my th400 after overhaul every thing looks good no problems in operation
so i got to thinking if using a different fluid is worthwhile are there any gains to be had
previously just used Dexron 3 I see in my searches some guys using Tractor hydraulic fluid
anyone have real world gains to pass on
Thanks
Royz

Be careful NOT to buy tractor HYDRAULIC fluid! It won't work. What we use is Hydratrans tractor fluid, which is made to work with tractor automatic transmissions and hydraulic systems. This stuff has the proper friction additives to make clutches and brakes work.

I've been running this stuff now for about 6 years and I've had zero problems using it. If memory serves, Beretta and several others on here run the same stuff. It is suppose to have better lubricating qualities and I think it will stand up to heat a little better.

Don't know how much truth there is to this but I read on a site online back before I ever started using it that B&M Trick Shift is the same stuff only with a blue die in it.

The stuff I use is made by Penzoil but they aren't the only ones that make it. There is no part number on the 5gal can I got but it does say Hydra-Tranz Tractor Fluid on the label on the front so yeah, it's the right stuff. On the back they list about 6 tractor brands that the stuff will work in.

Kenn, have you seen any tighter stall speeds with the hydraulic fluid?

I see some guys are running the AW32 hydraulic oil in glides and it is 10wt. I thought about trying some of the AW 46 or 68 that is 20wt to tighten my stall up some.

Are the AW rated fluids the ones you are saying to stay away from?

Not familiar with the AW hyd oils but I can say that if there are no friction additives in that fluid the clutch packs might have problems. The Hyratranz oil is heavier than regular ATF.

FYI, before I started using this stuff I used Type F fluid as that stuff has more friction additives than Dextron and there was a noticeable difference at the shift. The first TCI brake valve bodies I bought had that Type F fluid recommended in the instructions.

Not sure if the different fluids will yield a noticeable difference in stall.

I have been running AW32 for 3-4 years now in my glide. I had it apart the winter before last and the clutches were still like new could read the writing on the clutches.

So from what I gather the AW68 should be basically the same fluid, just in a 20 wt?

Here is what I have.....

http://www.warrenoil.com/product_warren_hydr.html

Warren Premium AW-68 hydraulic oil.


I am trying to get as much of a stall change as possible with my 8 inch. Cant go any tighter without going to a 9 inch.

From what that sites says, all those AW fluids are NOT transmission fluids. They are for hydraulic applications only and nowhere in those specs do they list any friction additives for clutch packs.

At the bottom of the page they do list the Tractor Transmission fluid, which is probably the same stuff I run made by Penzoil.

If you do decide to use that AW fluid, make sure to let us know how the clutch packs hold up. ;-)

Well, I ran it with the 20wt in today and it tightened it up about 200 RPMs.

Helped enough to cut my finish line RPM down to 7200 RPM but I think it hurt my MPH some.

Worked good enough to runner up in a 1K footbrake race..... =D>

From what I can see it improved the 60 ft about .02 but I can't really tell on the ET because we were running into a driving 8-10mph wind yesterday with higher gusts and my brick (68 Dart) doesn't like head winds very much.

That was some of the MPH loss I think too.
