What is the most common issue with the Kia Soul's transmission?

I have noticed that my Kia Soul's transmission seems to be shifting roughly. What could be causing this problem?

It is possible that there is an issue with the transmission fluid. It is recommended to check the fluid level and condition and possibly have it replaced.

Another common issue could be a faulty solenoid in the transmission. It is best to have it checked and replaced if necessary.

It could also be related to the transmission control module. It is important to have it diagnosed by a professional mechanic.
