WOT noise

Could be,but sounds like the tranny mount.Also could be motor mounts.Last week before I traded off the GT the motor mounts went...when I got on it sounded like a hammer hittin the frame.But my best and first guess would be tranny mount.Look at the rear of the tranny right where the cross member is at,look and see if the rubber between the cross member and tranny is seperated...if so then theres your problem.A bad tranny mount should make that sound everytime you pull out from a dead stop.
