I bought a used 2003 durango with the 4.7L and according to the stamp on the bottom the 45RFE transmission, and it runs and drives great! But i recently started having a problem where it jumps from D to R and won't display P on the dash. I have wrenched long enough to go through the usual suspects, and its not the linkage. I suspect its a neutral safety switch/range sensor. My local autozone has said part but i have looked on the transmission itself and for the life of me can not find anything that looks like the part. Link to the part included below
