2010 Silverado 4.8 engine for the last few days I have noticed a "wet spot" about the size of a baseball under the front of the truck right behind the bumper. I first thought maybe I had splashed through a puddle or something but on the 2nd or 3rd time I raised the hood and the oil cooler lines for the transmission were wet and had a drip or two of fluid on them. The truck only has 73,000 miles and this seems a little premature to have these lines filing has anyone else had this issue?
