| 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.
