shoey_R33 Posted January 16, 2004 Share Posted January 16, 2004 with my 33, when i clutch down from fully engaged, sometimes i can feel my engine 'jump'. it sounds like a dull rebound sound and i can feel the engine/box jolt. At high revs, it makes me misshift because it seems like the H pattern is slightly off its usual position (like putting in 3rd, instead of pushing the lever straight up, I have to move the lever slightly to the left then push up). could this be a clutch problem, or a collapsed gearbox/ engine mount etc?

GTR R35 Posted January 16, 2004 Share Posted January 16, 2004 sounds like a broken mount or possible backlash through the drivetrain. Easy way to check is pull your hadbrake on, put in gear and see if anything goes thump. my bet is a engine mount.

Bobjones Posted January 17, 2004 Share Posted January 17, 2004 I have a very similar problem, have checked rear gearbox mount, uni joints, diff, engine mounts and cannot find a problem. Am thinking its clutch related but do not have the time to pull apart at the moment...

Nightman Posted January 20, 2004 Share Posted January 20, 2004 I too have this problem, it seems to be if you do a slow mid-high rev shift... I think it is backlash (in mine anyway)... But i think my box is stuffed. Link to comment https://www.sau.com.au/forums/topic/32202-gearbox-jumps-when-clutching-in/#findComment-652220 Share on other sites More sharing options...
