Finalized PHENIX results are presented on J/ψ modification from the RHIC system-size scan, which include p+Al, p+Au, and 3He+Au (small systems) collisions as well as AA (large systems) collisions at forward and backward rapidity (1.2<|y|<2.2). Comparisons with state-of-the-art theory calculations and LHC data will be discussed. The forward rapidity data in small systems are well described by model calculations for all three systems, however, the backward rapidity p+Au and 3He+Au data are not reproduced by the shadowing calculation alone. J/ψ v2 meausrements in Au+Au collisions at forward rapidity is consistent with zero.
