Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.

Replace upper arm control
The light comes on but if I reduce speed it goes off, but will stay on after a while. It seems to hesitate going up inclines or from lights. Light stayed on for a day after town driving then went off. It only happens when I drive into SLC in fast traffic.
