I just bought a 2005 Honda Accord Sedan auto V6. After 100 miles I noticed that when I go from reverse to first gear, when it shifts into second gear there is a slight noise and I can feel that it isn't shifting smoothly underneath my foot. I don't have a problem with it from going to park to first, only reverse. My husband also can feel it. Honda techs are saying they don't feel anything. Has anyone else had this problem or know what it is?
