[H & E]

So I just got home from the dragstrip. It was 90+ degrees outside with about 95% humidity. I made 15 passes on the car with no issues. The last pass, I do my burnout and get them nice and hot. I launched at about 4500 and it actually hooked, pulled hard through 1st. Went to grab second and the clutch pedal was only about 3" from the floor. I immediatly let out of the gas thinking I blew the clutch out of it. I get back to the return road, pushed the clutch in and it popped right back up like always. I stopped, put it in first, took it up to about 3500 and dumped it. It grabbed like always. Now, when I got back to my pit, it noticed it did throw a code and made the SES light come on. I reset the battery and it went out. I also drove it back home apx. 30 minutes and it was like nothing happened? Anybody any guesses? Did it maybe boil the hydraulic fluid in the clutch?
