Erratic shifting Elantra 01

gman2083 · 11-03-2012, 11:09 AM

I have a 2001 Elantra GLS. The tranny shifts smooth. At around 40mph, it wants to shift into what I guess is overdrive. At that speed it is like it can't figure out where it wants to be and will down and upshift. Aside from that the tranny has no other problems. Any suggestions?

Did you have it scanned for codes?

maybe a "key dance" will bring up a code. Works on other cars with a digi OD.

Might be speed sensor. Code reader might confirm.

This might be a shot in the dark, but check the tranny fluid level. I was experiencing the same issue after I performed a full flush and it turned out I was low on fluid. Best of luck!
