Transmission code help

[austenthelemon]

Hello, I have a 2002 Ram with the 4.7 at 158k. Transmission acts up and upon scanning the codes I got:

P0700 - Transmission Control System Malfunction
P0846 - Transmission Fluid Pressure Sensor/Switch “B” Circuit Range/Performance

Looking into it, it seems to be the pressure sensor. Is that where to start first? I'm new with these ram trucks and would like some input and advice, also if it is the sensor where would it be located? Thank you for your time!

Not sure, just bought the truck a few days ago. The transmission fluid looks newer and doesn't smell burnt

I would drop the pan take a look new filters fill it back up with new fluid who knows what someone put in there.

We just changed out the fluid and reset the codes, code is gone and drives great now!
