I recommend that you contact your local dealer or trusted tranny shop ; maybe Level 10 or someone like that & get their opinion. I've been working with hydraulics a long time & your fluid can't be too clean::: but there are places/ shops that will tell you that your tranny may go out if you service it, because it will break loose some potential caked on dirt;etc...If you have it flushed; be sure they use a good machine or run it I between drain and fills... Mine took about 12ish quarts to get really clean....& I used Valvoline Max life Nissan S-matic approved
