leaking oil on 2000 GMC Jimmy

I have a small leak in the front of my car with the oil. I believe it is in the two hoses in the front of the car. It leaks when I turn my car off and there is oil all under the front of the car which makes me beleive that it leaks when I am driving as well. Is there anyway I could fix this problem myself or should I take it to a professional? I am pretty sure it is in the front two hoses because that is where the oil is and where the oil leaks on the ground.

Its sounds like your transmission cooler lines have a leak, You need to address this because if the line fails when driving it could damage your transmission. Have a mechanic check this right away.
Depending on your comfort level, and tools available, the cooler lines can be done. I do recommend finding a repair manual at your local auto parts store for your Blazer to have as a reference. You will need to refill any fluid that is lost during the hose replacement so make sure you have the correct type of fluid available at the time of repair.
