Hi I recently did a full flush and replacement on mine. I used CASTROL TRANSMAX Z. Here is the spec sheet : https://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/5318889C4CDA883380257C990001D228/$File/BPXE-9H7QZ8.pdf Its similar to Nissan where Matic Fluid D which is used by our cars. Been running it for almost 6 months now with zero issues. Hope this helps.
