Ran a back to back race this weekend in moderate temperatures. Did have some overheating issues as i worked to get around a car with more horsepower in the 2nd race and found myself stuck behind him for 49 minutes until i passed him on the last lap
. At the end of the race down shifts started grinding and when i got back to the paddock i could not get the car out of 1st gear unless i shut off the car. Any ideas what might cause this? Did i overheat the clutch or ?

Check your clutch pressure channel in Motec and make sure you weren't dragging the clutch. I've seen a lot of guys do it and not even realize their foot is resting on the pedal.

My newest 911 is a 993 but have had this problem in both the 993 and a 951. Grinding on downshift when hot says the clutch is not completely released. Suspect the slave or clutch master cyl is failing and result is a dragging clutch. Try bleeding first before replacing parts. A worn out clutch will likely slip instead of drag.

I agree with both of these before you spend the $ to drop the trans an inspect the clutch.
Also is your shop or you adjusting the clutch travel? If not you can burn a clutch really fast in these cups.
