RX350 Vibration
 

Hello, I have a Lexus RX-350 2007, American. After replacing the oil and filter in the transmission, when driving in tightness at a speed of 40-60 km, the car start to vibrate. I drive 1000 km after change oil, now there is a small hum. Before the oil change, everything was good and the gears shifted perfectly. I did the adaptation- not results. There are no errors. Before changing the oil was not dirty and odorless the combust
I am inclined to replace the torque converter. Can you please advise Your opinion.

Regards & good luck !
