Can't find that code in my 98 FSM.  Googled it,

P0705

Diagnostic trouble code P0705 indicates that the Engine Control Module (ECM) or Transmission Control Module (TCM) has received an input error from the Transmission Range Sensor (TRS). This switch is also known as a pressure switch, Park Neutral Position switch (PNP), the gear selection switch, or a PRNDL input switch.

That should be right on top of the transmission.  Do you have a replacement?
