will not recognize Park or Neutral

:runaround:My 2007 Dodge Grand Caravan with a 41TE transmission will not always recognize Park or Neutral. I bought a Neutral safety switch and had it replaced at a Transmission shop. They told me when I left that they had the same problem after they replaced the switch. I have to leave in the morning so I just took the van back. I was also a little frustrated with them because I paid $360 for this fix and they told me to come back when I get home and they can diagnose it for $75. Does anyone know what this could possibly be?

Not having shifting problems? It's probably either the wiring from the PCM to the instrument cluster or the cluster itself. If it doesn't shift right then the PCM or the wiring from the transmission range sensor to the PCM.

It shifts OK, It is sometimes when I put it in park it does not register on the dash causing the van not to start. I replaced the TRS Transmission range selector. That did not fix it. Please any other help would be great.
