I had the same issue for months and I just had it fixed no more noise it ended up being the middle bearing in the back part of the tranny there are 3 bearings in there and I had all of them replaced by a neighbor that works for a honda shop for 300.00 plus parts which were only like 80.00 his cost but its all better now I bet thats where most of your noise is comming from its kinda common he said
