Here's the latest UOA results for the ATF that came out of my Fusion's 6F35 Trans from my latest drain & fill.
At the time of the sample, the trans had 223,968 miles on it.
The fluid that was drained was a combination of Valvoline MaxLife ATF that was put in during the last trans drain & fill I did, and what remained of the previous fill, which I assume was Motorcraft MerconLV.
The trans has a fairly typical trans 'hum' when it's cool/cold, but other than that shifts remarkably smooth and doesn't exhibit any shift flares or shuddering. Based on that, and this trans fluid UOA, it seems it's still in decent shape. The numbers seem pretty steady, at least. I don't really know what caused the higher silicon, but I suspect it found its way in via the dipstick, or perhaps during the last fill..
