G6ET... 109ks on the clock, cars only had an entry level tune and has always been regularly servived.  When driving it cold at about 50km/h if I slightly increase the acceleration I can briefly hear and feel a shudder and vibration.  I can't pinpoint it but suspect it's coming from either the diff or gearbox.  It goes in for a service tomorrow and I wouldn't mind your thoughts on what it might be?   I'm hoping it's not the auto slipping.  It only does it when cold and at low revs - like around 1400rpm

 

Thanks for your help.

Just wondering when this started happening?  Was it after you had the tune?  That might help some others to give their considered opinion.

Ever had the ZF fluid and filter changed?

 

I get shudder in mine if it's the first few minutes of the day and I load it up too much but it's no longer a stock box - different clutch pack materials and different oil (Transmax Z).  Oh and it cops 50% more power than stock fairly regularly.

It's been tuned for about a year, I've only just noticed the issue, thanks

Yeah they seem fine, it sounds more like a grinding vibration, like something is not meshing properly which I guess if there were slop in either  mounts itcould cause the noise 🤔

Once car is all warmed up it completely goes
