Hi Jim-
I believe (according to the original operator's manual), the 2010s (H-L-R transmission) use JD 303 hydraulic oil. However I believe the consensus from everyone on the board here is to use Hy-Gard from JD rather than universal tractor transmission oil meeeting JD 303 specifications.
Universal tractor transmission oil meeeting JD 303 specifications could be used for the loader (or attachment) hydraulic system- they are isolated and seperate systems from the transmission.
