Mechatronics sleeve leakage
My car's warranty is about to be over, so I took it to an independent shop to do a thorough check. Good thing I did that, because the mechatronics sleeve was leaking transmission oil. (Not sure if the dealer would catch that while they change engine oil.)
The dealer replaced the sleeve under warranty and hopefully it won't be an issue again. While they were at it, I asked them to put in new transmission fluid, cost me about $120. (My car has about 25K miles).
Hopefully things will be fine with the auto transmission in the long term.
