Does anyone know the virgin TAN of this ATF?

Oil was changed at sampling with NEO ATF and a new Pioneer filter. 6 quarts is required to refill after the pan is dropped. The sample was taken as the pan was dropped.

87,101 miles factory fill pan dropped & changed with Coastal Dexron III & ATC filter
106,700 miles pan dropped & refilled with AMSOIL ATF & Deutsch filter
128,610 miles pan dropped & refilled with AMSOIL ATF & Hastings filter which is the current analysis

Any & all comments are welcome.
Looks like the auto-rx cleaned out a lot of stuff like iron and copper. Looks like you are taking excellent care of this car by changing this out. Wish I knew more about reading transmission analysis. I plan one on my Honda Accord at next 15,000 mile change.

I'm not going to do a full system flush even after adding the ARX. It ran about 3k miles & I guess 50-75% of system capacity is changed when the pan is dropped. I don't think it will harm anything even with the Neo fluid in there.
