I've owned my truck for 2 and 1/2 weeks now and it has not been above 20 degrees F, the truck did not leak when I bought it, it warmed up to 35 40 degrees the last few days and I noticed a spot on the cement at my parents house where I spent this weekend and the truck sat. I crawled underneath and it is wet around the oil pan and the bottom of the transmission, i can't tell exactly what it is because I'm sick and can't smell anything, any thoughts on what this could be or where it could be coming from, I couldn't find a thread on here discussing this and in a little worried

Clean it all off and recheck later. Is it not just from the drain plug?

Warmer weather thinned the oil out a bit. Many Duramax engines have small oil leaks that are inconsequential.

Ill crawl under her and clean it off, I checked the spot on the driveway and it almost looks too clear to be oil, I'll investigate and update with what I find out when I feel better and can smell again to figure out what is actually leaking

Oil will be black as night. Clear could be steering fluid.

Maybe. Find out conclusively what the color and smell is.

I think its a power steering leak I can't find where it's leaking from, and the motor is leaking oil between the motor and tranny

The power steering fluid was low, I added some and cycled it back and forth and discovered that it is dirty and there is particulate in the fluid, what are your thoughts?

Is it normal for the power steering fluid to have particulate in it like that? Or is there more serious if an issue at hand?

The power steering fluid can become contanimated because it is subjected to extreme temperatures. A simple oil cooler [like a trans cooler] installed on the return line, will help keep the temperatures in check. The fluid particles can cause a pressure problem and you can loose power steering and brake booster assist.

In the meantime best to do a flush like 07keo02 suggested.
