Well where to start lets see, about a month ago i noticed a clanking noise when putting the car in to reverse almost like when there is load on the linkage that changes gear i get a loud CLINK sounds metal to metal, it doesn't sound internal. Sounds like something is loose well of course the dealership couldn't replicate the problem. Now while im driving with the car in gear and it is in the higher rpms like right before its getting ready to shift or if i put in into the passing gear I'm getting a weird noise almost sounds like a rattle or a zzzzz lol i cant really type how it sounds. now if i put it into neutral and rev it, I do not get the noise only when its in gear, it gets really loud when i step on the gas. Another thing i took off the cap that's on the transmission am I supposed to able to see fluid in it? also why in the hell is there what looks like a plastic wire loom in it. Any help would be much appreciated, Thanks in advance

Did you try the cobalt forum? Someone might know something over there.

 

Did you check your inner CV joints?
