Smelling it in my crosstour as well. With only 3.5 quarts of maxlife put in. Strangest thing. Didn't spill a drop either.I had the exact same problem with maxlife, after I purchased my 2012 odyssey used at 60,000 miles i did 3 drain fills (not spilling a drop) in the first week to clean out the dark oil.
I used maxlife on my previous 2001 odyssey after the rebuilder of that flawed transmission said use nothing but maxlife.
Anyways the 3rd drain fill change I used DW1, as I suspect the transmission was running hotter on maxlife hence the smell in the interior.
The smell was gone...
