Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. 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.Google+

The Vehicle Shutters from 2nd to 3rd gear. The computer is not showing any codes. The dealer has Flashed the computer system and this has not corrected it. It only occurs when the engine is cold and after it warms up it goes away and shifts smoothly. I had it to a trans repair and he states it's not the trans. It's also been newly tuned up. No one knows what's worng or how to fix this.
