Hi Guys
Thanks for a very informative forum. Best to all for the new year.
If any one could assist with information regarding a whistling sound when the 2010 Gen 4 3.2 DID Lwb changes from bottom upwards through the gears, especially when cold.
All else seems fine. Could it be a hydraulic valve that resonates before opening fully? - only my guess!
Best to all
