automatic transmission fluid question

[DaFinksta]

I need to add some atf to my truck, but I don't know where to add it. I read in the owner's manual that it's a cylinder. I saw a cylinder next to the atf dipstick, but couldn't figure out how to add the fluid or get the cylinder opened. Any help would be appreciated.

You add it through the ATF dipstick hole.

I just add mine through the dipstick tube. I think that's the only way.
