99 Odyssey with 282K on her. Just got back from CO towing 3
motorcycles (~1800 lbs) and a fully loaded car. I think nothing of
getting on the road with this thing.

In her earlier life I towed a piece of equipment that was later to be
determined to be 860lbs over the limit (they forgot to weight the oak
skid it sat on :) ) That tranny lasted 188K. Latest one I have been
running AMSOIL (www.amsoil.com) Honda fluid. I have to say after
religiously changing the fluid every 30K on the honda...I now can
actually go 90K (it's in need of a change). Close to 30K with the
honda fluid you can feel the shifts getting old. About 94K on the
Amsoil.
Time for a change now..~$8.50 Quart.

Tow to your little hearts content.
