Track Z making funny sound?
 

OK so we were mocing the track Z the other day a few blocks down the road. When I noticed it was making a very funny sound. I think it's the tranny because of the lack of tanny fluid. But I'm not sure if it's the engine. It's making like a fast tink sound. Has anybody ever played Grand theft auto? The first one and when your car is about to blow up it would make that tink sound? Well that's it. And I sure as hell don't feel like dropping in another engine in that thing
