03 Liberty 3.7 Transmission Line Pressure Sensor Location - at a loss

Hey all, I’ve been looking for the line pressure sensor/transmission fluid pressure sensor on my parents’ 03 Liberty 3.7 for quite some time and am at a loss for its location. I looked at a few service manuals which indicated it was on the rear passenger side of the transmission just above the fluid pan, but i looked around the entire pan and only found the speed sensors. For context, its throwing a 841 code.
Does anyone know where it could be?

What transmission do you have? I think some early 03s had the 45RFE and later went to the 42RLE.

Is this it?
For 42, the pressure switch is attached to the valve body.
There is an exposed upward facing connector on the right side of the transmission, but it cannot be replaced from the outside.

Sorry for the delayed response, i had to go count the pan bolts. It should be the 42, but the sensor i have has a bolt hole so i dont know if it would fit there. Could also be the wrong part though. Here’s a pic of the new sensor. Thanks for the help so far!
