Causes and Fixes P0748 Code: Pressure Control Solenoid “A” Electrical

How to fix P0748 Code: Pressure Control Solenoid “A” Electrical
A P0748 code is set when the computer (TCM/ECM/PCM) detects an issue with the Pressure Control Solenoid “A” located in the transmission.
The pressure control solenoid regulates hydraulic pressure in response to throttle angle, engine speed, and prevailing load requirements.
Fixing a transmission can be difficult since there are often many small components.
Possible Causes of a P0748 Code:
Low/Dirty Transmission Fluid
Bad Pressure Control Solenoid “A” or Wiring Issue
Transmission Issues (Pump - Valve Body - Blocked Passage)
Bad Computer (TCM/PCM)

I'm replacing the valve body on an 06 Kia Spectra. Do you know if I have to have reprogrammed? I have this code also p0700 and p0748. Car goes into limp mode once a week. I already changed the input output transmission speed sensors and did a transmission fluid flush and new filter I'm trying to fix this issue where it goes into limp mode and get stuck in third gear. I turn the car off let it sit for 10 minutes turn it on everything works perfectly. So I'm changing the valve body out and need to know if it has to be reprogrammed after I do this or if there's any other options to reset the shift patterns and can this be done with a ODB reader

I'm not sure on the year but I believe it will need an Adaptive Reset. Here is a video ruclips.net/video/acqwTQwVQYs/видео.html
