Static transmission fluid leak at the drivers side under radiator

[rrh13441]

Need some help here. I have a 2012 GmC 2500 HD LML that is fully deleted plus EGR and PVC. Recently I noticed a small leak under the drivers side up next to the radiator crossmember wher the radiator rubber mount is. I pulled the tire and wheel well cover and it appears there is transmission fluid that leaks statically. Not sure where it’s coming from. Here is a picture of that area and as you can see there is wetness on the rubber mount and the cross members. Any suggestions on what this could be?

There are no transmission lines/fluid on the driver's side. Maybe power steering fluid? Or just some coolant? Outside possibility it s the trans cooler leaking, but not at all likely.

You got a radiator leak and ill bet thats a mishimoto radiator leak (absolute junk). No full aluminum radiator stands up in these trucks. Go get a factory radiator and put it in. The plastic tanks far outlast those aluminum ones.

You’re correct it’s a misimoto radiator and intercooler.

Well you beat the year or less nate figured you’d get. I was in the same boat as him lol.

Also be prepared to swap your Mishimoto radiator out in about a year or less. Anyone looking to put a Mishimoto radiator in needs to search the forums. They are junk. But anyway hope you have your issues resolved for now.
