The other day, my 2006 F-150 broke down on me while I was driving on the freeway. Before the truck completely shut off on me, a warning saying transmission fault appeared. My truck won't start and I haven't been able to take it into a repair shop yet. My husband is good with cars and he thinks it has to be something electrical. I was just wondering if I could get some suggestions as to what it may be and figure out the cost of the repairs.
