We just bought an 1996 Aerostar. Over the weekend my husband put a stereo in it--as soon as he was finished installing it the odometer would only flash, the speedometer would not work and the tranny will not shift while driving-it just winds up really high then if you really push it it will shift--He says he checked the fuses and they are all fine and we can not figure out what he did or why this happened--If anyone has had this problem or knows how to help us out please let us know---Thank you
