Make sure that the car was leveled.
Did you keep an eye on the temperature of the transmission when you were filling it out.
And yes, the exhaust is right near the fill plug, I burned a hole in my transfer pump, good thing that I had a backup one.
For the liqui moly containers, they are designed with some kind of filler tube, I popped the that thing off so I could put my transfer pump in it.

I have 125k on my transmission, still shifting well. I might check the level also when I do the transfer case oil change.
