Recently done a pan drop, & filter change.
Sent a sample for analysis before, & after refilling with new oil. I would estimate I got about an 80% oil change
Not much of an increase in Iron, & Copper from the previous analysis, & oil viscosity still within range.
Slight increase in Aluminum, which was flagged at Upper Critical.
There was some minor filings on the filter, & Pan magnet, but very minimal to other transmissions I have worked on.
Oil is Mercon ULV ATF
