I went to a casino with a parking garage that is a straight incline all the way up and over-revved when trying to accelerate up the hill. Since then when I've been shifting to 2nd and 3rd gear, it accelerates to almost 5000rpm every time. 4th, 5th and 6th seem fine and they haven't accelerated to a high rpm, but 2nd and 3rd seem to go to 5000rpm probably 50-75% of the time I shift to them. Is there anything else this can be other than my clutch slipping?

 

I broke my clutch drag racing, but with the wrong technique, I suppose it could be done on an incline.

Slipping has little to do with the gear. If you move into the torque band, the clutch will slip. It cannot hold the torque.

 

Yea, I've never had to deal with hills because I live in flatland Ohio.. what is the 'right technique'?

 

Possible glazing of the flywheel? Goes away with a bit of driving. If it stays or gets worse, may be just the clutch slipping and needing to be replaced.

 

Went to go drive around today and the car would barely pull out of my parking spot. I got it to the Nissan dealership and they were surprised I got it there.. apparently it needs a new clutch haha.
