I have a 2006 forenza, 5 speed manual, 138500 miles, 4 cyl, America. Had trouble bleeding after the slave cylinder was supposed to have been fixed. Got stuck in fourth so we bought a vacuum and we bled it. It drove great for about ten miles and is now stuck in fourth again! We just put a new clutch master cylinder in but it is still stuck! Is there a simple fix we’re missing?
