Question: Codes ?

[Diesel Pilot]

My brother has an 01 dually with 120k and he is going to be making a very long haul trip in the next month or so.

He said it was shifting hard on the 3-4, and sometimes it won't go into Drive or Reverse. Also, it never goes into R when in 4 LO. (I'm guessing the going into gear problem is the NBSU)

Here are the codes I pulled from it today:

P0700 TCM MIL Illuminate
P0841 Transmission Fluid Pressure Sensor A Performance
P0846 Transmission Fluid Pressure Sensor B Performance
P1710 Pressure Switch E Stuck Open/Performance
P1711 Pressure Switch E Circuit Low

Alright, what if anything is wrong and should it be gone through befroe making a 4800 mile trip?

Also, the truck doesn't have any tune on it. Completely stock, it just pulls heavy loads all the time.

I would bet that the converter clutch is going out and there is dirt in the valve body sticking the E shift valve.
