So about a month ago I was driving down the road, going to work and I gave my car some gas and I felt the transmission slip. So I started messing around with it. And noticed it would only slip in 6th going at a decent speed and I gas it, but its still not every time. Its more like once or twice a week. My question is it more likely the clutch or the gear?? And if it’s the clutch iv herd that you cant resurface the flywheel so im looking at either the z1 motorsports clutch kit or the jwt kit. I have a 2004 G35 Coupe with aobut 93 000 miles on it.

 

Clutch is the likely culpret....Gary

 

most likely the clutch..

 

Like they said - probably clutch. If you don't notice it slipping when starting you should have a little time to shop around for a new one. Have you tried downshifting to say 4th on the highway and giving it gas to see if it is slipping there too?
