Transmission went out while I was going down the road

Hello, Start by checking your transmission fluid. If it is low enough you will not be able to drive. If you find the transmission fluid is at a normal level (with the engine running and warm), then you will need to visit a repair facility. Here is a link, and you may want to call and ask the different shops if they offer a towing service. It could save a little on the towing/repair combined.
