Unable upshift to the highest gear when terrain off

MyD3 is 4.4 V8,
When terrain mode is turned off, it is difficult for the transmission to increase to the highest gear.
When the terrain mode is "Grass/Gravel/Snow", the transmission is normal and can reach the highest gear.
In addition, my manual transmission mode is not working.

There are no fault codes including transmission, engine, terrain mode, HDC...

I know that the transmission program varies depending on the terrain mode, but currently I don't know where to check because there are no fault codes. Please provide suggestions

Does it make a difference if the headlights are on? If yea, resolder red wire splices in the floor.

Otherwise, get sports mode working first. Look around the gear selector.
