I experienced a noise and judder. We had transmission fluid drained and replaced and it fixed the problem, thank goodness. We were told by a Honda Service guy that it sounds like the transmission was going out. I called another Honda dealership and the guy suggested we drain the fluid and replace it with Honda transmission fluid and see if that takes care of it, as that is what they would try first. Was happy the guy gave me this info and saved us $$.

At low speeds there's a thump sound under the rear axel. The dealer can't figure it out at all.
