I have this sedan 3.8L Genesis, 120,000 miles. Great car so far.
It seems to have a sealed transmission. I don't know if the previous owner ever had the fluid changed, so I am thinking I would have it done.
My question is: Is this something I can do myself (I'm very handy with a wrench)? Should I? Or, can any mechanic shop do this or should I go to a dealership?
If I do it myself, what do I need to be concerned about?
Is there a filter that should also be changed? Should I drop the pan? Should I drain and fill all the fluid or half of it.
Thanks for any help.

 

Not knowing past maintenance history, you could run into some problems.
I would suggest you consider having the dealership do the first change and once that works out OK, you might consider doing the next one.

 

Thanks. I was leaning that way. I just never liked dealerships.
