Hi. Wondering if anyone can help. I have a FL2 i6 3.2 HSE Auto 123k M. On some jouneys, not all, and particular journeys slow in traffic or in hot weather, the 3rd gear struggles to connect (over revs before jumping a bit before getting into gear). When this occurs I also get a loud clunk from the rear diff area whenever I put it into reverse. I know the haldex pump needs replacing and overall haldex servicing and I expect may need gear box oil replacement soon, but any ideas welcome! Thanks.

I would start by changing the oil in the autobox as well as servicing the haldex and rear diff. Then see what its like after that. Jules
