1996 CHRYSLER CONCORDE
My husband, 2 children, ages 4 and 6, and myself were driving on the interstate when our 1996 Chrysler Concorde suddenly shifted into neutral and started rolling backward down a hill. We hadn't had any problems up to this point. Our car only has 40,000 original miles on it. A transmission repair firm told us it was our transmission and gave us a diagnostic code of "P1787". We can't afford to fix right now. We have tried it on our residential street and it goes for a few yards and transmission slips. I have had a lot of medical problems this year and not having safe transportation has made it impossible to get medical care, not to mention the fact that my children could have been hurt by this vehicle malfunctioning.
