    Mine popped and and I felt something hitting under the center console. Turned out it was a broken transmission mount. When I shifted hard at High rpms or mids it would do that. Check it out.

    Does the shifter jump around when you hear the popping noise??

    Could be a broken transmission mount. If the mount is completely broken, the shifter will tend to jump up and down when you shift.

    No nothing moves when i hear the popping noise it sounds like its coming out of the exhaust to me but the popping i only hear when i take off first thing in the morning or its been resting for a couple of hours after it warms up i dont hear anything after that.

    You mean regular shifting or power shifting? If it is power shifting you could be hitting your rev limiter.

    sounds like you're describing the exhaust popping which is normal with free flowing exhaust. Do you have an aftermarket catback?

    i believe its jst a normal thing with cars like ours, because mines does the same thing until its warmed up. i think it has sumthing to do with unburned gas fumes that are hot hitting the oxygen mollicules in the air and combusting... i could be wrong though
