Paid Hyundai Dealer $85 to relearn (reprogram) trans, did not help. After driving approx. 50 mile or more, come to a stop, trans would shift very hard from 3rd to 4th gear or engine would rev when making this shift. Hyundai Corp. no help as they say never heard of this before. They want mechanic to drive around block to see if trans will repeat problem. Traded this van to a Dodge Grand Caravan, at least they don't charge you for a trans reprogram
