Hi! We need help with our 69 Camaro 350. There is a vibration coming from the engine that travels thru to the tranny area. You can hear and feel it when the engine is being revved in the driveway or during acceleration when driving. We thought it might be the water pump going out and replaced it. Didn't fix the problem. All bolts have been torqued to their specs. Belts are tight. No leaks. No loss of power. Any ideas? Thanks. Karen.
