Got emailed back my used transmission oil sample results. There was so much iron and copper content that the lab could not perform some tests. A screenshot is attached.

ELEVATED IRON MAY BE SOURCED TO BEARINGS; GEARS; SPLINES; SHAFTS; HOUSING; NON-MECHANICAL ORIGIN. UNABLE TO TEST
FOR PARTICLE COUNT (ISO CODE) DUE TO EXCESS PARTICULATE. OTHER READINGS APPEAR TO BE NORMAL. CHANGE OIL.
RESAMPLE TO MONITOR.
Iron 585
Copper 952

After a month of use I will re-sample the new oil, to determine if the new filter and existing mix left-over in the cooler and torque converter will become back to acceptable levels.
