Skoda Superb 2009 5 Speed gearbox problem

[skodagordy]

Hi, I have a 2009 1.9 superb which has done a trusty 163k miles without too much fuss until now.

The 5 speed manual gearbox/transmission has developed a chattering sound on take up and on pulling uphill (under load). The problem was thought to be gearbox related so my local specialist pulled the box for inspection. The Clutch had done 70k and was worn and was replaced with the DMF. The gearbox was stripped and nothing was found untoward and all was reassembled back in the car with new oil.

The car still clatters on take up and two drive shafts were fitted as the next cure but to no avail but did lessen the noise.

Any help would be very much appreciated.

Check out engine/gearbox mounts. Try rocking the engine backwards and forwards. I had a chattering/knocking sound on load with my Octavia that took some tracing. It was the engine mount attaching the top of the gearbox to the chassis - replacement solved the issue. Initially visually the original looked fine but it had devoleped excessive movement.

 

[EDIT] - I tested it using a paint brush handle pushed into the mount. Clearly a lot more vibration detected but no chatter!

BIGJOHN, Many thanks. Well worth a try. (The chattering did lessen after the driveshaft installation.)

Will post again with the result.
