I could not recreate the problem this afternoon - I drove around for close to 45 minutes on the interstate near our home but didn’t lose the clutch on highway exit. I don’t know if this would be enough time to heat to the point of failure, so I am torn about taking my car to North Carolina versus the small sports car my husband has. Could it be coincidence that this problem happened after my fluid change? Could an incorrect fluid cause the same symptoms? They charged me an extra $30 for some synthetic stuff they said was required, but the other person said it looked dirty to him.
Thank you for the advice though - if it happens again I will see if the water helps.
