I just drained my JD303 spec hyd fluid out and installed transmission fluid.. I hope it will handle the heat a little better without thinning out.. I have been having problems with my hyd fluid thinning out while working the tractor hard in the extreme heat , creating very little flow to operate the loader, and the tractor it's self is very slow to respond
I think it will make it worse to be honest. ATF is usually 10W20 and I.m pretty sure the hydro/trans is thicker than that without researching it. It will be better in the cold weather for sure but not the heat. Although my YM14 runs J spec ATF fluid which is thinner again and it's fine in the hot weather. I guess all you can do is see what it does :2cents:
