2004 XC90 T6 Gearbox noise

[jsck4303]

I am an American living in Germany and have a 2004 XC90 T6 with 94K miles on it.

My problem for which I need to see if anyone has had the same issue and can advice is:

while I am driving and accelerating, the car respond perfectly. I have no problem switching on or off, nor breaking.

But while I am driving, as soon as I remove my food from the gas pedal, I hear this noise like an engine sucking air or slowing down. I have no fault messages in the computer. Service was done, few months back.

If I go fast, say 120KM and remove my foot from the gas pedal the noise is loud, and as I break or slow down, the noise reduces accordingly to the speed.

I have the car in a repair shop and their believe is that there is something to do with the gearbox. I would like a second opinion.

Anyone answer will be greatly appreciated.

Is this the original gearbox? If it's related, they had issues

Check all turbo and intercooler plumbing for loose clamps or tears. Check and see if your CBV is working properly.
