Transmission Range Sensor P0706 etc codes and emergency starting
I suppose this is just an FYI or informational post. Had a new (for me) issue last weekend). I was about 15 miles in towards a campsite on a dirt/4x4 road. Transmission started hunting gears and engine surging. OD light started to flash, transmission moved into a single (high) gear and manual gear selection would not effect gear.
Got to my site late and troubleshot in the morning.
Threw P0706, P0707, P1702 codes--which all indicate Transmission range sensor (or possible PCM) issue.
Ignition key did not engage starter solenoid. = No start.
Tried cleaning the terminal/plug connection at the tranny and disconnecting batteries to reset PCM. Also tried clearing codes with my Edge Insight.
I was relieved to find that at least this situation the PCM only disables the starter solenoid, not Fuel, etc. I was able to jump the starter and solenoid terminals with a screw driver and limp my way home in 4th gear (guessing, maybe 3rd).
Waiting to get it into a shop to drop the tranny pan and check the TRS.
Just an fyi that if you have an electrical No Start, it is worth powering the key on and jumping the starter/solenoid to get yourself out of a sticky. In my case this would have been a very tricky flat tow, and a very difficult trailer extraction.
