2007 Honda Civic si transmission repeated failure. Third gear malfunction diagnosed and repaired. Shortly thereafter second gear malfunctioned ,fixed, happened again exactly as first malfunction with second gear. Car at dealer twenty-eight days and counting (may 24-June 22,2011).
I was shifting easily from 1st to 2nd gear at 15-18mph and approximately 3k rpm. My manual transmission failed at that time, and I lost power-- nearly creating an accident. The failure involved broken teeth of the countershaft and final (ring) gear. This type of failure has been documented previously in many internet forums, but perhaps not formally. Honda should have information about models experiencing such failure, represented by the number of transmissions / countershaft / final drive gears sold by their parts distributor. As a physician, I feel that Honda should recall these vehicles immediately to prevent serious injury & road hazards from this transmission failure-- raymond bernal, m. D.
