This is from my 2003 Sable with the AX4N / 4F50N. There were 16570 miles and 34 months on the Motorcraft Mercon V as of the sample date. This Mercon V was in there as part of a full cooler line exchange. However, it went in after 36,000 miles / 6 years and replaced Motorcraft Mercon V that had turned light brown. Calcium seems low but wear levels look good. I understand that solids are the clutch pack materials so this reading is especially good? I read that TAN above 2 indicates an ATF change is due and 3 means the ATF is worn. I have anyhow done a through the dipstick drain and fill which replaces 50% of the fluid. Any thoughts on future intervals for 50% changes? I calculated that 50% changes every 10,000 miles equate to the recommended 30,000 mile full changes.
