3rd and 5th indication sound
 

Well, I've had my truck for approximately 6k and 8k miles. 5th and 3rd create a strange sound, since I've had it. It gets worse, for the stick and sorta shake it in the apparatus. It creates the sound continuously until I simply take my foot off the petal or in 5th once I look for a constant pace. Simply take moist mud in to both of your hands and rub them together. This is actually the only way that I will actually discribe what it seems like. What's up with this? Can I be worrying or such a thing?
