Bentley Mulsanne makes a whining noise in gear, who do you trust for it?

I have a small problem that keeps bothering me, so I want to hear from other owners. I have a 2013 Bentley Mulsanne and I use it for business trips and special family days. For about two weeks now I hear a soft whine when the car is in gear, and it gets a little louder as I go faster. It goes away when I slow down. The car still drives fine, but I can feel a tiny shake when it changes from second to third gear. My brother says big cars always make some noise and I should not worry. My friend has an old Arnage and he told me a whine can mean old gearbox oil or a tired part inside, and that waiting can make it cost more. I did not know who to believe, so one night I read about it online. I opened a page about Bentley cars on a Sharjah website to learn how the gearbox, the oil and the sensors work together. It said a small noise can be an early warning, and that a scan and an oil check are the first steps before anyone opens the gearbox. That made me feel a bit calmer. Then a coworker told me to look for a Trusted Bentley automatic transmission specialist in Sharjah, but he also said I should ask a lot of questions first. He said a good place will show me the fault codes and the oil in simple words, and will not rush me into a big repair. I liked that advice because I do not know much about these cars. So I have some questions. Is a whine that gets louder with speed usually the oil, or can it be a part that is wearing out? Is it safe to keep driving the car for work while I wait to book a check? What should a garage show me after the scan so I know they did a real check? And about how long does a first inspection take, and what is a fair price? If you had the same noise on your Mulsanne or another Bentley, please tell me what it was and about how much you paid. Thanks a lot.
