Out, 5.5 quarts of ATF+4 and one bottle of Lubegard red with ~25K miles
In, 6 quarts of ATF+4, Four Valvoline, two Supertech.
The extra 0.5 quarts was because of this new addition to the cooler circuit: That is a fram XG16 on the Derale external filter mount
Shifts faster and firmer with 6 new quarts of ATF+4.
I'd also dropped the pan after draining by aftermarket drain plug welded to pan with no interior nut, and cleaned the magnets.
The donut magnet migrated to the Neodymium magnets I place during last pan drop.
That donut magnet is not very strong. I used the stronger magnet from my deleted Magnefine filter on replacement, in addition to the two Neodymium magnets.
I've not yet lined the new external fram ultra XG16 filter with magnets, but the priceless warm and fuzzies are now in full effect.
