Had a flush done with Amsoil multi-vehicle ATF and a new Wix AT filter installed. The viscosity dropped low enough that it started to impact shifting when pulling a fully loaded trailer. Luckily it doesn't look like any damage was done.

I presume this was the factory fill?

Not bad, overall. Perhaps time to change, but nothing alarming at all. The report shows there was life left, but if performance was altered, it's was time. The Amsoil "ATF" will likely last a LONG time.
