Anyone else having clunkyness in the driveline at bumper to bumper speeds, ie going up/down 1/2/3 gears?

Mines had is since new, reported it twice and both times the software was apparently upgraded as per the latest TSB's, last time was about 4 weeks ago. I'm not 100% sure its coming from the trans, could be coming from the diffs and I find I end up driving it in peak hour to try to make it not clunk, it's not a metallic sound so maybe more of a thunk, but it's quite noticeable for even my wife (who doesn't care about refinement), normal driving, it's smooth as silk.

Just wondering if it's the nature of the beast or is it wrong?

Some owners have reported this, lots of reports from the US owners. Sometimes the software updates fix it, sometimes not. Sometimes a relearn helps.

Cheers Benno, I don't really know what the dealer has done of course. They may well have done a re-learn now that you mention it, my wife reported it was much better after she picked it up from the dealer but it progressively got worse which would indicate it's coming from the trans.

I'll have a look around the US section and see what the latest is there.

Hi guys, new to this forum. anyway i've got a 2013 MY14 diesel with 60 000k on the clock with this slight clunk/thump was very noticeable mainly 2nd to 3rd upshift.

Went to the dealer and test drove with the foreman. Was told it's the transfer case binding up.

Told me to change transfer case oil and add LSD additives. so far so good it kinda is still there if you're really looking for it but it's nowhere near as bad as before.

So you might have the same issue i'm not sure it's just that this fixed my problem.

Thanks
