i went with redline fluid and the atp pan/filter. got the redline through
@Nick@GotExhaust (vendor on here) and pan on rockauto. i had no issues since the service. atp pan has replaceable filter so if you decide down the road, you can replace just the filter.
one piece of advice: measure your clearance between exhaust and pan. i struggled mightily getting the stock pan off. literally no room and the exhaust doesnt move much there. i actually broke off little plastic pieces on the valve body getting it off. atp pan cleared no problem going on as it is a little shallower (not enough to matter). watching videos on youtube made it look easy and no issues. but my truck was a little different.
