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.

1999 Hyundai Elantra shifts hard. When warm or hot, down shifts are very hard and makes a clunk sound. Had xmsn serviced and the problem still exists.

Auto Transmission shifts erratic at times, even when backing out in Reverse. Put in new fluid at 72000, helped some, but the hard, erratic shifts are still there.
