My 04 Odyssey 3.5 V6 is a 5-speed auto. I'm almost positive this is the same.

My results match, especially the dip at 43 mph. The shift points are 10, 20, 30, and 45 mph. See that last one? It doesn't match. The 40-45 mph span is just painful as the engine revs but won't shift. I generally try to keep it below 40 or above 45. You can do a quick D-N-D shift and get it to shift sooner, down to about 42 mph.
