Possibly. One of the failure modes that has caused warranty
extensions/recalls involves clutches disintegrating and clogging the little
(inaccessible) screens they have in the fluid passages. This then causing
exciting behavior like slamming into 2nd gear without warning at 80 mph. I
suspect there would be less chance of that happening if there was a filter
in the pan (if it had a pan...). It would still disintegrate, but the
failure mode probably wouldn't be as exciting.

It does make for easy fluid changes though.
