I recently bought a used 2004 Nissan Sentra Spec V with 54000 miles (standard transmission). The test drive went great and I noticed no problems and a basic inspection gave me the OK to purcahse the car. However recently I have begun to notice a scraping/metal-on-metal noise when I let the car slow down in gear. Just as it reaches the range of RPMs where a downshift is warranted the noise begins to emanate from underneath the car. It is alleviated when I press the clutch. It happens in all gears though not as noticeable in higher gears such as 5 or 6. I'm bringing it in to a good mechanic but I'm worried this might be the start of a transmission problem.
