Dropped the tranny pan and filter, cleaned magnet in pan. Pulled drain plug on connected diff. Fluid was opaque brown, but no burnt smell. ATF could be original with 160,000 miles. After another drain and fill dirted the fluid quickly sent sample in after 500 miles.

What fluid did you use for the refill? It should shift better after that service.
Valvoline Maxlife ATF, shifted a little better. never slips just hard shifts from first to second, little shift flare from second to third.
So based on this analysis, would you folks recomend a flush using the trannies own pump to get all that suspended metal out of the transmission. I can take some 3/8 line and connect to return on tranny cooler. Or does it apear this tranny is on it's way out.
Crickets, how about using Lubeguard Flush additive first, then flush. Then replace all fluid in tranny with Valvoline Max Life ATF. Have a 2,000 mile round trip to Indiana soon!

I'd skip the additives and continue the drain and fills.
I know it is not a good idea to shock the system with a power flush. However the Blackstore analyst I called after the y esting, stated that dtain and fills would not likely remove enough fluid. Also with this much suspended Iron and Aluminium ie. insoulubles the current is sandblasting the internals of the tranny.
Ened up flushing tranny and refilling with Max life ATF. Much firmer shifts at anything other than WOT going up hill. At WOT shift flare bad between 2 and 3. But if you back off the throdle it shifts and goes on it way. No slipping so far but only be a few hundred miles.
I bet the metals are left over from factory fill never being changed.
