I Have now heard the 3500 RPM death rattle today while merging with traffic with a cold engine. I was hoping I would not be affected by this problem. I dont drive the Bullitt hard when cold usally shifting before 2800 RPM. But today I had to make a quick run and traffic was heavy so I had to smash the go pedal, 1st gear 3500 and there it was. I tried to duplicate the sound while parked and could not get it to do it. I'm so bummed!
