2018 Mirage SE, 15k Miles
Photo makes the old fluid look much darker than it actually was. Next service will be at 30k miles when I change the Aux filter again and drain+fill. Going to be sticking with Amsoil CVT fluid.
New filter came from cobra transmissions (just search for the JF015E on their website). The new filter seems to have many more pleats and a slightly thicker material. No info on what the filtering capability of either is though. I didn't end up needing to replace the o-ring. Whole procedure was pretty easy.
