I'm really surprised there is no check engine light as this has to be affecting emissions. Based on the rpms and noise I would lean towards a speed sensor or more precisely the problem with the gear meshing of the speed sensor, broken teeth etc.
Codes need to be read before doing anything as I see it. I expect a transmission code to be in there of some sort at the least.
I don't know your area and the quality of the dealerships. Dealerships are only another shop under the manufacturer name brand. They are only as good as the individual techs and the ethics they follow. Some are great some should be run outa business. Independents are no different. I find there are a cut of independents that are above most, but finding them isn't always easy.
