I think my auto tranny has gone crazy. First of all my tranny quit working about a month ago, so I had to park my car and start saving some money to fix it. It didn't shift into any gears, and then after I tried and tried the whole engine compartment shaked up and down as the auto tranny tried to shift. Then after the car had been sitting in my garage for about a month, I went up to get some stuff of my car and decided to give it a try, and guess what the tranny worked!!!!! It went into Reverse smoothly and drove like it had never been broken. I even tried it on the highway because I couldn't believe that it was working. Does anyone knows what happened???

Is it safe to use the car now?? I don't want to be driving my mom's old car. Please let me know.
