Transmission?

I have a 2007 Dodge Grand Caravan with a 41TE transmission, I have been having problems with it not recognizing Park and Neutral. I took it to the shop (after my dad tried fixing it) and they replaced the Neutral Safety Switch. $360 later, when I picked up the van today they said they had the same problem. I need to leave in the morning so I was kind of stuck into leaving with the same problem I started out with. Anyone have any ideas what else this could be?

Does the van crank and start okay, or is it the display on the cluster that is the problem? It does not have a neutral safety switch it has a transmission range sensor. If it cranks and starts in only park and neutral then more than likely that is not the issue. You could have a communication prblem between the PCM and cluster, or a cluster issue. The wiring diagram will show you what I am talking about.
