So last night a buddy and me were logging my car and after my last 3rd gear pull I did a pull in 4th and after I hit redline I threw it into neutral to cost to a stop and I wasn't paying attention but my buddy taps me on the shoulder and says "look!".. my RPM's were stuck at 4K and weren't dropping until i hit the clutch again.. i think its maybe happened like once or twice before but i paid no attention to it. I mean I'm not showing any signs of a bad clutch. I did a pull in 5th at 30MPH right after and no slippage. Any ideas fellas?
