When doing a transmission service, has anyone gone to the trouble to dismantle the filter to inspect it? If so, how dirty was it after how many miles? And how was the integrity of the filter holding up? Have you ever seen a filter compromised?

I've never done this, but plan to at my next service. It seems like the condition of the filter should tell us something about the condition of the transmission.

FYI there are some Youtube videos that show people dismantling their filters.

Thanks.
