I have not experienced any problem with the transmission overdrive but Kia as a car manufacturer are great at offering free access to training information and workshop manuals on line for free.

I had the same problem. My thermostat was faulty so the engine coolant level was below 68C. If the coolant temp is below 68C the auto transmission won't change to overdrive. This was easy fix for this kinda of problem.
Good luck with yours.
