The 2003 pilot is making growling or grinding noise from what I believe is the transmission. This happens when I am pressing down the accelerator slightly at speeds around 25 mph, 37 mph and 48 mph. I have also experinced the car stuttering once but has not happened again. I had the transmission recall serviced but the noise started around 30,000 miles. I have read someone writing on this newsgroup about the same problem. If you are the one that have written about this problem, please send me an email and let me know how the problem was resolved.
