i took 2018 gt350 to the track, and when i shift from 3rd to 4th, the clutch pedal stayed down and won't go up in at least 1 sec. i thought i was doing money shift and try to hit the clutch and i didn't find it.. so i have to press the clutch for 1 sec until i let it go for the rest of track day. it only happens on track not during normal driving.
