i fitted some powerflex dogbone bush's the other day, and an hour or so of driving after fitting them i cant always get second gear anymore. The gearstick seems to move into the correct position but then springs out as soon as i let go, if i let go of the clutch whilst trying to hold it in 2nd it makes a grinding sound asif its resting against the gear but but it feels like there is something stoping it going in. I dont think it is syncro as ocasionaly it will go in no problem without rev matching. Any ideas would be apreciated thanks
