Yeah thats pretty much what I found. In N my fluid level went higher, but still within range.
Well its 3 source vs 1 now. The owners manual, the factory service manual, and a CSR representative all say the dipstick is "wrong" and the "correct" method per Chrysler is to use Park. I'm amazed that they haven't updated the dipstick yet.
Only way I can really see using Neutral being an issue is if you fill it on the "low" side. Since I found the N reading to be higher, you may end up slightly under-filled.
