Does anyone have any input as to why a new clutch assembly would have a vibration/pulse in the clutch pedal shifting ONLY from 1st to 2nd (slightly starting to feel it from 2 to 3, but mainly 1st to 2nd)? If you guys remember, Infiniti replaced the clutch assembly due a poorly seated flywheel. I broke the clutch in for ~800 miles and haven't done anything too strenuous. Note: did not pulse during the break in period...and YES, I've been nice to it (extremely). Thanks in advanced guys!
