Have it scanned for codes to see if it may be an electrical problem like maybe the switch on trans auto parts can do it for free, if no codes show up then have it looked at by a trans guy as it may be something inside trans. It sounds electrical to me like either a bad switch or a wiring issue or maybe the tcm which tells the trans what to do.
