So I put in a new clutch last year. It works fine in winter but this summer and last summer it does a weird thing. It almost seems like when it's hot outside my clutch pedal will go from having lots of clutch to play with to barley no clutch to depress at all. Also if I kick on the clutch pedal a couple times it's like it resets the clutch pedal back to normal but 10 shifts later and I'll have little clutch to play with again. Anybody know what's going on?

 

I've had my trans out twice before today and both times it was fine but I needed to bleed it once more as everything worked out
