What is the code PO700 from ECM, It said to check transaxle system. on 2007 Kia Sportage

My check engine light came on and the code P0700 from the ECM.

You will need a shop with the proper scanner to get into the transmission side of the system. P0700 is just telling someone with a basic code reader that there is a code/problem with the transmission.
