C5X7 2014 2,2L HDi gearbox clunk

[ozzdownunder]

It seems that when after initial starting the engine and placing the automatic gear into drive it clunks into gear. Once into gear it changes normally without any clunking. I have read that the gearbox oil in these cars never requires to be replaced? If you have had the same issue, how was this resolved?

Ok, have started with replacing the gearbox oil with the first 3 liters. Already it has improved and noticed gears are also smoother in changing. At this point there is no clunking noise. Will drive it for 3000 km or so and refresh the oil again. Thanks to all that have responded to my query.
