09 grand cherokee 4.7 4x4 at slips bad DTC P0841

So I just inherited a 2009 Jeep Grand cherokee. its a 4.7 L 4x4, when shifting into reverse long pause and hard shift, long delay but does get going and not so bad when driving.
check engine lamp on and
DTC P0841 - trans fluid PSI sensor switch A circuit range performance
P0732 - gear 2 incorrect ratio
P0731 - gear 1 incorrect ratio
p0876 - trans fluid PSI sensor switch D circuit range performance

I am thinking about starting with a fluid flush and new fluid, replacing internal and external filters and replace TFPS Sensor !!!

would this be worthy or is trans smoked ? I can do all the work myself, I'm just trying to repair it VS new salvage unit........

thoughts ???
I am an XJ fan, this is a whole new beast.............

what are common reasons this happens ????
