Trans fluid.. what kind?

[Desert Bred]

What suitable type of transmission fluid do i need to replace with in the trans assembly?

I would be a help to say what tractor you are talking about, however most tractors and those with wet brakes will use the Universal hydraulic fluid designed for tractors with integrated reservoirs for hydraulics and transmission.

Hi Gary. AW32 i'm assuming. Well, I have a Taishan 254 (25hp 2cyl 4x4) - i know a bit odd but a nice machine.

AW 32 is what I ran in my Yanmar 4220D. You may could even use AW-46 in Arizona for the summer heat. IIRC AW 32 is about 20W oil whereas AW 46 is 30W. I think either one would work. If it has wet clutch and wet brakes (meaning they are in contact with the hydraulic fluid) then make sure the brand you use says that it is compatible with tractors with those items. Most of the Universal oils are. I have been using Super S Premium hydraulic in my tractors and just put it in my B26 Kubota TLB rather than use the high dollar Kubota oil which I doubt is any better. I don't use the SUDT2 anyway as my Kubota dealer says that it is a waste of money for our mild temperatures regardless of what many post here on TBN about it being superior, etc.

Thanks Gary. Without manual..or only pieces of a manual so your input was helpful. Just checked and it has an air brake system.So AW32 it is. Thanks again.

Ok so I went to change the oil, and underneath I found 3 plugs.

The two on either side of the middle larger plug had nothing to plug (nothing drained out).

The middle one gave about 3 gal of a caffe latte colored oil.



My question is Those two plugs are (guess here) for the rear axle differential while the middle is for transmission (?) Also ,

what do you make of that Color??

If your tractor hydraulics uses a common sump with the the rear axle, you should not use an AW series oil. It's strictly a hydraulic oil that won't do the gearing any good. You need a UTF type oil (Universal Tractor Fluid). You owners manual should specify the oil in the rear axle/hydraulics and the transmission. They are often the same type oil.
The AW series are strictly hydraulic oils used in "pure" ( not drive gears or transmissions) hydraulic systems
