Problem Description and Possible Solution
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.

After 3 hour trip at highway speeds, transmission shifted hard once at street speeds. did it once, then nothing... wonder if the deaqler will blow me off like everyone else?
55,000 Rough shifting even after transmission replacement at Hyundai dealership. Unable to go smoothly under 40 MPH. Car does not coast, but slows to a stop going downhill unless gas pedal is depressed. On flat roads at speeds under 40 MPH, the car is constantly shifting (even with cruise control) and making the ride very choppy.
Had a problem after highway driving of one hard shift through lower gears. That no longer happens. Now there is hard shift around 40 mph going from 4th to 5th. This is very predictable happening all the time. I'm not sure where to go with this since I have no confidence in my local Hyundai dealer's maintenance department.
