I had my transmission overhauled at 78000 miles, now I'm at 83000 and now is not working. It was acting up during the summer and is just sitting in my driveway in gear just doing nothing It feels like it will go but is not grabbing. As I checked the coolant level I noticed a layer of transmission oil floating on top. Did any of the coolant seep in to the transmission? Also, other than the radiator where does the transmission receive cooling from?
