Soft clutch 2nd to 3rd and 3rd to 4th

8800 miles...2015 GT M82

Steeda return spring..

Noticed this at the track the last outing and its now feeling the same on the street..

1st to 2nd is fine, feels great, 2nd to 3rd, it almost feels as if it's slipping for just a half second or less and has no firm "snap" into gear as it used to. 3rd to 4th is similar. This is at WOT for reference.

Other wise, no slip in any gear at any other RPM usage.

Maybe the Steeda spring has lost tension? The pedal feels kinda soft actually.

Air in the system?

Anybody have anything similar happen?

Ever find a fix for this issue? Looks like I'm having the same exact problem with my car.

It can't be air in the system. If there is air, you would have the opposite issue such as the clutch won't disengage or you can't shift into gear when stopped.
I have heard some people are having issues at higher rpm operation as the pressure plate starts to lose pressure on the clutch.
