"Inspect" Automatic Transmission Fluid?

I just finished up the 30k service on my 2013 Tacoma. Easy peasy. But the last thing on the list is to "inspect" the transmission fluid. How does anyone inspect fluid? Is this just a top off scenario? Not even sure I want to mess with ATF at 30k miles. This is a Toyota after all.

 

I checked mine at 20k and I was 3/4 qt. low. There’s a good write up in the 2nd gen. maintenance sticky. You need to check it at a certain temp with truck running.

If it was my truck I would do a drain and refill with Amsoil. It is very easy to do, especially when you have a car lift.
