What does detonation sound like?

I'd be wary of it if it does it under acceleration and stops when you let off. That sure sounds like what it's doing. It doesn't always sound the same on every engine, so be careful.
Thanks Rob I was hoping to get your opinion. It got dark on me so I had to quit im gonna work on it some more. Looking like I'm gonna end up dropping the trans pan again its still leaking like a slave :BangHead:
