Default P0843 P0700 trans codes

Driving home from work on the freeway with cruise control on a little above 80 my engine light popped on. I stopped at Advance Auto Parts and had them scan my engine getting two codes.

P0843 Transmission Fluid Pressure Sensor/Switch "A" Circuit High
P0700 Transmission Control System Malfunction

I haven't really notice any problems other than under light throttle car seems to sputter/hesitate like a misfire but its only on rare occassions. Car shifts without any clunks or hesitation. Anyone experience this?

Car has 193k miles w/rebuilt trans at 135k ( from original owner) who knows he could have gone through 5 trans for all i know. lol

If I'm not mistaken the fluid pressure sendor/switch controls the pressure for the whole trans and is a common issue for failure. I could be wrong
