Hello all,
What does Roush do when their sbf engine developes a vibration? No, I haven't contacted them yet. At first this slight vibration was felt at 2200rpms in 5th gear about 55/58 mph. I thought it was chassis related until recently when it happens in all gears at 2200. My installer is still scratching his head. Yes it vibrates in neutral at 0mph too. There is none at 2150 and none at 2250. Anybody experience this anywhere? I received the car/engine trans new in July and now I've got 4600 miles. I guess you can say the vibration is a tad more than new. Cliff
