I recently tested my Fiero...After about 10 laps, I came in only to discover that I could not get into or out of gear (s)...After a "cooling off" period, it worked well again...until it became "hot" then no gear selection.This was an all day adventure. Does anyone have any suggestion as how to cure the problem? I was using DOT 4 fluid. I was thinking the heat from the exhaust was heating up the slave causing some moisture. Looking for any help! Thanks! :
