Most posts on the forum seem to advise against a reverse flush, and recommend just dropping the pan, draining what comes out naturally, then refilling. Do this several times, and you've got almost all new ATF.

Rationale for not flushing is just what AAMCO told you.

I read one post where a guy did a forward flush and had no problems, and a few others have done reverse flushes with no problems. My guess is it depends on the shape of your tranny.

I've also seen recommendations to reverse flush the tranny cooler in '92s to make sure the mesh isn't clogged up.

Never done any of this myself, so I can't attest to any of it.
