I am getting ready for my pretty much annual Tranny fluid/filter change within the next few weeks since I have a 1,000 miles trip the GP is going on in early June-25,000 miles since the last change. I will report back on the fluid and pan condition at that time. I have been using Dexron VI for the last 5 years-Walmart Supertech and a Wix filter-Apprx $50. The pan is always super clean and the fluid always looks real good.
