Question for the Oil Gurus

Lynn Patrick · Mar 31, 2023

I have a 12 volt hydraulic pump that says use only Dexron ATF (w/no numbers following) or "damage can result". Is my 134 fluid the same or is there something special I need to look for?
Thanks!

I'd follow the directions then there is no question.

It's not the same. The Dexron ATF
is General Motors old transmission
fluid. You can find it anywhere.

What model of FORD? 134 was the N-Series hydraulic oil, no longer made or supplied by CNH. After te NAA and up oil s[ec was fdiferent, most no longer made either but
ATF is highly recommended these days for all FORD hyd systems.

My typo mistake! I meant 334.

I don't know what 334 is.

What the heck are you talking about? New Holland still sells a 134 spec fluid:

https://www.newhollandrochester.com/shop/73344280/

They didn't even create the original M2C134 specification until years after the N series, NAA, and even the 1955-1964 and 1965-1975 tractors. The Operators Manual for my '73 3 cylinder 4000 calls for earlier specs than the 134 spec, like M2C41A and M2C53A, which were later superseded by the 134 spec.

What to heck does the model of Ford have to do with the 12-volt hydraulic pump originally asked about?

The 134 will likely work fine, at least in warmer temperatures, however if this is a small closed system, you aren't talking a quantity of fluid that will have a significant cost difference, unless you have leaks and are losing fluid. In that case repair any leaks and just stay with one of the Dexron grades. The newer Dexron III, IV, VI, etc. grades are all backward compatible as far as I know. Just my opinion.

I'm no oil guru. If the unit says Dexron put anything you want in it, it's your pump. If it fails it's your pump so what we say means nothing. If the pump company thought enough to spend the money to put a sticker on it saying Dexron I guess that's what's compatible with it.

dextron had... more anti friction additives than the equivalent ford type F family of fluids m2c53. m2c134 replaced the type F due to the '78 ban on whale oil viscosity additives, so probably would not have the needed antifriction additives as dextron did. But 134 was good for tractors with wet brakes and wet clutches so that they would not slip or chatter. So... if that that application has any wet clutches or wet brakes, then 134 would probably work. If not, the dextron might make the pump last longer.

No, they are not the same.

Thanks All! I bought a couple gallons of Dex for it.

Do you have a reference for this?

Thank you
