P0868 P0934

Hey guys and gals got a question for y’all

My truck has around 80000 miles on it and been blessed by ray at DRD since new I think it had 20000 on it everything has been great but now I’m getting a transcode first it started with P0868.

GOVERNOR PRESSURE SENSOR VOLTS TOO HIGH so I changed the sensor out for new one but not a Mopar one.

The light went out and code clear but I noticed the line pressure was bouncing all over the place from 95-120 real fast not stable.

Drove for a while and no codes then now it’s pulling code P0934 LINE PRESSURE SENSOR CIRCUIT LOW.

Maybe a bad sensor so I order a Moparreplacement one and I’m going to change the filters too.

The transmission seems to shift fine it doesn’t slip but just wonder if there’s anything else that I could look into? Also does anyone else’s line pressure jump around and not steady.

Also forgot to add both batteries are a year old and I tested them they all past and my other code is for grid heater replay high voltage.

When was the last time your filters were changed?

It’s never had the filters changed I just ordered new Mopar ones today.

I’ve never had good luck with aftermarket line pressure sensors on 68RFEs.

Yeah that’s what I was thinking too and the new one just came in today so when I change the filters I’ll change that too and see what happens.

Just an update I drop the pan today and the fluids look good it was ready for a change it was a dark red smell clean not burnt and no trash in the pan at all just light coating on the magnet.
