It was fine when I left there, I stopped to get coffee and came back out to leave and that is when it started happening.

 

It is possible that it is the TC, though it is weird that it suddenly came on right after an oil change. If it sounds like it is coming from under the seat it definitely could be TC noise. Sounds like that may rule out engine noise, though vibrations do travel. When my TC went, I caught it before it started vibrating too much. I noticed the subtle whine immediately and took it in the next day. Drop some oil from the TC into a magnetic tub of some sort. If a ring of metal forms, that's bad. Good luck!!! Also, I had an aftermarket clutch disc/PP and they covered it under warranty, but I searched hard to find a good dealer.

 

one of those lube dorks probably sabotaged your car due to low self esteem / jealousy / mental illness.

 

another reason I don't go to PB. My old car had to stay there overnight and the next day there were dents and scratches all over the driver side door. It was obviously from them getting in and out af the car with a screw drive or something.... Never again.

 

I think it may be my cat who knows its at the dealer. We will see tomorrow.

 

when i changed my engine oil , the engine did sound noticeably louder.
the thinner oil seemed to create the noise 5w-30

 

did you visually inspect your engine to make sure nothing is loose?

Under the car as well?

Are you sure it's not your tires?

is your streo on when this happens?

did you check your side skirt connection?

 

Yes i did check everything, and it looks fine. The dealer said they could find nothing wrong with it either, (they forgot to change my TC fluid) It still is vibrating and is louder than before. Taking it back on friday to have the TC fluid changed. The car feels restricted, like somthing is holding it back a bit. It had new plugs and all fluids except the TC today. still sounds the same.
