I think I found your report though I'm not sure...I did a search based on your city and looked for samples from 2012. So assuming I'm looking at the correct report, it was a factory sample from your truck? I do see potassium and sodium in the oil, and those are markers for coolant. We did not highlight and talk about them because the levels were low enough that we assumed they were just leftovers from the factory that would wash out with time. Sometimes we'll see those additives in factory grease, and we try to err on the side of caution with new vehicles. All kinds of things show up in factory oil and we'd hesitate to call anything a problem without seeing a trend, just because most dealers would roll their eyes if a guy took his factory sample oil analysis to them and complained.
We check for water using the flashpoint test and it only detects water at greater than 500 ppm. So if there was less water than that in the oil, it would not have shown up.
Transmission oil mainly contains phosphorus and a little zinc, and those are the same additives used in engine oil. So when a little transmission oil is added to a sample of engine oil, we can't rely on the additives to "see" it. if enough was present, we would see a diluted viscosity. You did have a light viscosity, though you didn't mention what grade it was supposed to be. A lot of factory oils are 5W/20 and the viscosity of your sample would qualify as a 5W/20, but if your factory oil actually was a 5W/30 and transmission oil was added to the sample, that would explain why the viscosity read light.
As I said before, we test every sample and we'd be happy to give you a tour if you're ever in the area. And if you do ever sample with us again and aren't happy with the results, please let us know! We never mind rerunning a sample to double check results or re-doing the comments when we get more information.
