Automatic transmission flush

Hello, I have a 2019 SR 4 cylinder with an automatic. It has about 63k on it and the transmission has never been serviced. Operation is fine but I would like to do a fluid/filter change if possible. I have been told it is sealed. Can I work on it myself?

 

Welcome!
It's all right here my friend, a very comprehensive list and videos.
I did a drain and fill (essentially a partial) at 45k miles, and I would suggest you do the same. After that, keep doing drain n fills every few years or 30-40k. It's cheap n easy and a hellva an insurance plan.

You wouldn't happen to know what kind of transmission fluid the 6-speed auto takes, would you?
