Have not made it to the dealer yet as today is Sunday. I most likely have transmission cooler/radiator failure. As I learn more, I will update the thread.
Plan for the day was to change oil/trans/front dif/rear dif/and transfer case fluids. Did oil first, then moved on to transmission.
Didn't like the color, it just seemed "off" to me. Had the "Oh chit!" moment as the thought of radiator to transmission cross contamination came to mind. Went to the radiator overfill and didn't notice anything to scare me. Went to radiator cap, and there it was, a strawberry shake in the cap.

Through this, I learned a couple of things that would be helpful to others:
Noticed a vibration around 30mph on Thursday of last week (4 days ago). Seemed like turning OD off solved the issue. Felt like very worn rumble strip. Find similar vibrations on concrete highways also.
Autozone has a part that would work if the Nissan part was not readily available.

No parts are actually needed to do this beyond the vacuum caps mentioned in post #1. Reason being if you follow the passenger side hose up the side of the radiator, there is a splice (shown in post #1) already there. Remove from the splice to where it was originally attached, and the driver's side hose will reach to that location. Here is the section of hose that I removed that went from splice to passenger's side radiator.

Here is the location of the splice on the passenger's side of the radiator.

Specs on my truck = '05 Nismo w/ 77951 miles March build date. So, for those with '05 frontiers, it might be worth it to do this as others have had issues.
