If they claim the transmission fluid was "flushed" I'd like to know how. Really the only way is to remove the heat exchanger and install an adapter plate or an exchanger with with external transmission fluid lines like most Nissan's have.
You'll be happy to know I just did an oil change on a 2015 with 383xxxkms/238xxxmiles. No signs of transmission failure. Yet. Now it will fail tomorrow.
