karlp2 Member 81 Member For: 10y 8m 11d Gender: Male Location: Auckland, New Zealand Posted 06/08/16 11:27 PM Share Posted 06/08/16 11:27 PM (edited) 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.

Was it after you had the tune? That might help some others to give their considered opinion. 1 Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

I was wondering about the universal joints? lewis Link to comment Share on other sites More sharing options...
