I have a 2006 T5 4 Motion which has done approx. 130,000 Kms. When changing up from 2nd to 3rd it does not change smoothly, some grinding during gear changes. Going into 3rd is the only gear where this occurs. I have drained the G/B oil into a clean container and have not seen any contamination. I then put new oil in and still have the same problem. I think the syncro needs to be replaced? Can anyone recommend a gear box repair place with a good reputation?
