help plz AVEO 2010 1.2L MANUAL WHEN I REVERSE THE CAR JUMP AND JERKS ..

Hi i just bought a 2010 aveo 1.2l petrol with manual transmission.
When i reverse the car seems to vibrating jump and jerk it feels like it may stall , drives fine no slipping clutch , no knocking etc in all forward gears , the clutch seems i light high ..
Any advice please ? Clutch or gearbox fault or mounting

I would take a look at your engine mounts and see what condition they're in. I've had this problem on other cars and that was the issue.

Check engine and transmission mounts.

Also, you might want to flush and bleed the clutch fluid.
