Trans fluid/Tractor fluid?

Post by ventura74 » Mon Sep 07, 2015 7:48 pm

Anyone using tractor fluid in place of ATF for a street strip car? I've heard a few good things just need some opinions from people that actually use it. I've been just using dexron with lubegard for years. Any info would be great thanks.

The german buses (mann) that were used in mass transit in the 80,s would not warrant any trany rebuild unless traction fliud was used in the rebuild. Had less probelms with it than with dextron. I mixed dextron and tractor fluid together and ran it in a 550- 575 hp torqueflite. never had any issues with it.

Do you mean Hydraulic fluid like is used in hydraulic rams? I would of thought it too thick and slippery...

No not regular hydraulic fluid it's the tractor fluid used in the transmissions and hydraulic systems all in one. It has friction modifiers in it I've heard a lot about people using john deer light weight fluid

Hi.
im a forklift technician and we use what is called multi tractor oil(cat oil) , shell calls it spirax trans oil and engen or mobil calls it multitrak oil. All the same and does same thing.. Its used as hydraulic oil in all our machines and in tractor transmissions and in the small forklifts trans instead of atf. And has normal friction plates, and the bigger units its used for braking system and cooling there of its hydrostatic brakes.
Its multi grade at 10w30 as with our climate a normal straight 10 weight overheats quickly. Its less prone to foaming up as to speak and stays clean longer and i know of one guy that only uses hyd oil in his glide and th350. But he has phosfor bronze friction plates so dont know if it is of any difference with sae10 vs dextron 3.
hope it is off help
cheers

Years ago, I gaumbed onto 5 gallons of a water clear hy-fluid that I think was used as the working fluid that powered the railroads Track Tie Replacement Machines. They had 3-71 GMC's as power units that ran the hy-system. No mechanical links at all! The "Tie Saw", The "Scarifier", the "Tie Handler", the "Tie Inserter", the "Tie Spiker"......

Anyway, Mom had a sale when we left the farm and our neighbor up the road bid on it and was tickled pink when he bought the stuff.

I figure he was going to use it in his Model 60, JD tractor hy-system?? But really don't know.

I bring this up here because I always thought that "hy-fluid" was red colored and not clear????

From an older post:

Bracket Racing ATF

I've known a few racers that use the JD equivalent and like it.
(most are PG trannies though)

Use the JDM J20C" specification like the last post in that thread suggests.

Years ago I remember some people using Mobil lube 424 in their racing transmissions. If you compare this to dextran you will find it to have much higher specs. I used some in a Taurus and it reduced the torque converter shudder quite a bit. The only thing is it says clearly on the can"not for use in automotive applications " I don't know why unless it has some compatibility problems with the clutch disc material. It worked very well in my transmissions.

I tried john deere fluid in a TH350 as a top off when it leaked. It did not last long after it stopped, now that i think of it . Related to that or not i dont know. The torque converter didnt seem right with it. Again. I dont know. The tractor worked ok though..... :lol:

Bruce Toele used to recommend Mobil 424 in the 200-4r, he was one of the premier builders till he had health issues & closed up shop.

700r4. Was running low, pumped 2 quarts of type f in, and it barks tires 1-2 via 4.3 with unknown converter. I used to run hydro in my saturn and the now bare frame blazer. It's all stall speed and action.. You want it thick and low? Hydro is thicker than type f fluid.. Expect an RPM drop.

Will it work, Yes..

I've been using this in my 2004r for a couple years. Working well so far.

Is the tractor fluid the blue stuff that's synthetic?
