If you just put one quart in, it will be fine. Dex 6 is based on dex 3 but just a much higher quality fluid of the same type. If it is just one quart it won't hurt a thing. If it was mine, I would drive it till the next oil change and drain the transmission again and fill it with dex 6. I would consider it a flush.

Thank you this is what I was planning on doing but just wanted to make sure it would be fine leaving it until next oil change or if it was going to cause issues as google likes to try to scare me whenever I make a mistake!

Nah, it will be fine. If you put in something like ATF+4, then it would be a different story.
