Tranny fluid

[ULYCYC]

I ran Mobil 424 tractor fluid for many years without issues.  But it's really overkill on a basic build and may even lower your stall speed. If you have a trans brake and stall speed above 3800 then it becomes a asset. Check with your builder before you use it.  Also all tractor fluids are not the same. Check the spec on Mobil 424 and make sure its the same or better.

We had 55 gallon drums of Mobil 424 where I used to work. We used it in our front end loader transmissions. I think we paid and evnironmental clean-up company to haul the stuff off when we closed down. I could have saved the company some money by adopting it and bringing it home.

So how does this 424 compare to the aw68 rating? There is also an aw 32 and aw42 though I guess I need more reasearch as I don't know what these all mean.

Since I'm the "builder" I am not sure. I hesitate to use the term, I'm more of am assembler with help.

I'm not sure on how those rating relate to Mobil 424.  Many years of research and a lot of pro's use the Mobil stuff.
