Went to a dealership to have my oil changed at 37560 miles and was told I needed automatic transmission fluid along with a brake fluid change I'm the original owner and my vehicle is a 2013 G37 sedan

What is your question?

I was told the automatic transmission fluid needed to be changed at 30K and that I had gone over it. The service man said not to let it go on much longer? Is this dealership taking advantage of me because I'm a female? Told the Power steering fluid needed to be changed along with the other fluids
