Coming home today i went wot in 2nd and at 5k rpm the car hiccuped or stumbled and then was fine from 5500+ til i shifted at 6200 and was fine through 3rd. Is the clutch slipping or is there someting wrong with the opti or what?? btw i have a 94z m6

 

A slipping clutch won't cause engine stumble. You would see rpms increase without the car moving any faster.
