Well, C Tree PO, more often than not it seems that driving the car hard is actually
less risky than putting around at low rpms in high gears. It's not necessarily 100% fact, but those who have had experience with receiving/repairing cars with this failure have found that the cars were not driven hard or driven on track. Keep the RPMs over 3,000 (but below 4,000 until the engine warms up), and drive it however you like from there. Babying the car may bring about exactly what you're trying to avoid. Besides, the engine sounds way better past 4,000 RPMs.
