I went to AAMCO Transmissions & Auto Service to get a second opinion. I had gone to another shop and they said I needed a new engine in my Ford F250. I took it to AAMCO and they discovered that it was just a sensor. They saved me about $3500. They replaced the sensor, did an oil change, put in a new fuel filter, and got me all fixed up. I even had them work on 2 of my other vehicles. One of those vehicles I thought needed a new transmission and they discovered it didn't. They saved me another $4000. I was very impressed with them. I would highly recommend them.
