I have a 2009 Tribeca that had issues with flares between shifting. The dealer reset the computer a couple times that did not help, then they replaced the torque converter that did not help, then they replaced the computer control that did not help. After all that they decided to replace the transmission with a factory refurbished transmission. This helped the shifting but now I get an annoying whinning noise (kind of like noisy tires) that starts at about 25 mph and up. The faster you go the higher pitched the noise gets. The noise is loud enough to hear over the fan on high and over the radio. It is the loudest between 30 and 45 mph. It makes the noise when you are at a steady speed and when you are slightly accelorating, it goes away when you leave off the throttle. It doesent matter what gear the automatic transmission is in, it has to do with the speed. It also makes a gear noise when you are coming to a stop. I have taken it to the dealer several times and there service manager tells me he doesnt hear anything that is not normal. I have taken it to a local transmission shop and they have told me it is not normal. These noises started once I got the new transmission. Has anyone else come across anything like this? Is it normal?

Could be that the differential backlash or some other tolerances were not set properly by the re-manufacturer, but that's only a speculation.

You could take it to another Subaru dealer and ask them to test drive without disclosing the history then ask what it would cost to repair the problem...
They might not think it's so "normal".
If no other dealers are accessible, ask to have a meeting with a district manager and let them demonstrate the same sounds/conditions of another Subie on their lot.
You know your car. Unfortunately, because of the history, you have become acutely aware of the car's behavior as you chronicled it being "repaired".

Thats what it sounds like to me. A whine or raor that changes with road speed is usually the diff.
