No Idea what's going on

This started about a couple weeks ago:

When accelerating from 60 - 70, it seems like there is a "chug" somewhere. It's not the engine, but it feels like something is slipping. Is this something I need to worry about??

check your transmission fluid, sounds like about the time the torque converter would lock out. low fluid/incorrect fluid/old fluid could cause it to be a little rough. no CEL or o/d light flashing?

I'll check after work. No CEL or O/D light flashing. The 4wd lights did flash a couple times last week...
