Okay. That is good news. It is unlikely that the gas cap is causing a misfire but let's stay with the shifting issue on this post and then we can get another one started if any of the codes come back.
I am interested to hear more on the transmission being overfilled. Can you check it again today and see if it is still overfilled or has become overfilled again?
If so, you have a leak between the transmission and transfer case and more than likely the transfer case fluid is coming into the transmission. It normally goes the other way and fills the transfer case, but it is odd that you would get an over filled transmission unless you or someone previous to you getting this vehicle over filled it.
However, an overfilled transmission will cause all sorts of shifting issues so if you have not checked the fluid in a little while, let's do that and see where it stands today. If the vehicle is not acting up, then that is great and let's just see how it goes until it starts doing it again. We can't fix something that is not broken.
Thanks
