I have a 2011 RTM5, here the last few days, it seems like I hear a noise when I accelerate in first- third, then it quits. I have to really get on it to hear it too. If I just normally go through the gears, I don't hear it. It sounds like sorta a speedometer cable on an old car a little bit. If I'm in fourth-fifth, and get on it a lot it won't do it. If I'm in third once I get up to like 35, and get on it it won't do it. Seems like it's just in the lower gears, and only when you get on it. Maybe it's did forever, and I just started noticing it. Anyone else ever had something like that ? Thanks
