The clunk happens randomly but always sounds the same at any speed above 40mph. It does seem to be at its loudest when the car is at operating temperature.
I've been contemplating a couple things it might be that I haven't checked yet....a buddy of mine suggested that the flywheel maybe be catching and making the noise. Another possibility is it's something to do with the traction control, When the tires break loose and the traction control activates, as it nears the end of its cycle, there's a loud clunk as if the car is being forced into a gear or something (this maybe nnormal, i don't know).
I have yet to find out how the traction control ties in to the transmission and if it has anything to do with the abs?
