I was driving from Ohio to Oklahoma when all of the sudden the wrench light came on and smoke was rolling behind me. I pulled over, opened the hood and noticed transmission fluid all over the place under the hood. The fluid looks like it boiled out around the cap, if that's possible. I had absolutely no problems or indication of a problem before this happened. I caught a ride and picked up transmission to add back to see if could drive it somewhere off the interstate and afterwards it ran fine for about 2 hours then it happened again. What could be the issue here?
