[Solved] 2014 Toyota Sienna - noisy transmission after CV axial work
Watched your show for a while on YouTube - Thanks! Have problem. Last week I had to replace both lower control arms on my 2014 Toyota Sienna LE (FWD - 120K miles - no engine codes). During the repair the mechanic said that he discovered the driver's side CV axial was torn and slinging grease in the wheel well area. Since he was already replacing the control arms, I said to go ahead and replace the CV axial too. About an hour into the job I took a look to see their progress. I discovered they had the engine jacked up either on the oil pan / transmission pan (couldn't tell). When they removed the CV axial a of fluid came out from the transfer case. Mechanic said he poured back 2 quarts back into the transmission. Mechanic then drove the van to get the alignment completed - had to drive down the street as he didn't have the equipment.
When I got the van back, I didn't really notice anything immediately wrong. I drove home - no leaks. But when I restarted the van a few hours later, the transmission seems to be making scraping sound. I called the mechanic and he said he didn't hear such a sound and he swore he installed transmission fluid. I didn't get a warm and fuzzy. Took the van the dealer the next day to have them drain and pour transmission fluid in case the mechanic didn't pour the correct amount (or any). Dealer did the job, and didn't say there was anything wrong.
Again, after the van cooled down the same scraping sound at lower speeds was evident. I'm worried that the goober mechanic broke something and won't fess up. Again, no leaks. Doesn't make any noise in reverse, just lower speeds - highway speeds you can hear a high pitch sound. Any recommendations is appreciated.

It's called an axle, and FWD vehicles don't have transfer cases. The axle seats right into the transmission.

It could be a lot of things. Changing the axle might have just made it more noticeable.
Symptoms sound typical of failed wheel bearings.
