So i just bought a 2003 Nissan frontier 4cyl. Since i bought it it has made a slight rattling noise comming from the tranny. Now in my previous car when a thow out bearing went out it made a similar noise but the truck isnt as noisy and not nearly as deathly sounding. I have never owned/driven a 5 speed truck before and havent owned a cylinder motor in 3 yrs. Is it me just hearing typical noises in a truck tranny or should i take it back to nissan and have them look at it, and its still under warrenty
