Honda transmissions do not have bands like most manufacturers. In fact, inside they look more like manual transmissions rather than automatics. Also, there is no good way to drain the torque converter either. The Honda protocol is 3-4 partial drain/fill cycles. Pathetic, IMHO. (Or is it arrogant/optimistic?)
Insufficient oil capacity/flow (which causes high temps) and undersized clutch packs seem to be the popular diagnoses.
Our '03 Odyssey is okay so far, but I'm worried. I've switched to Specialty Formulations' Z1-equivalent to help with fluid temp capacity, and have added an aftermarket trans cooler. I have replaced the teeny ATF filter that Honda put on, and am planning an extra spin-on filter as well.
