This should be clarified a little. Understand, the purpose of double-clutching is NOT for matching engine revs to tranny. It is for matching input shaft to output shaft rpms WITHIN the tranny. Greater wear occurs when these two shafts are turning at significantly different speeds. I say this because many times, people think they are double-clutching when they downshift without engaging the clutch in neutral in the sequence, when in truth, they aren't. Simply revving the engine to match rpms to car speed will produce a smoother transition to the lower gear for the driver, but not necessarily for the transmission.
