Tranny problem...maybe
 

'06 Sonata GLS V6 AT. Had my first transmission "misfire" on the way home
tonight. Was using the manual shifter, going from 2nd to 3rd. Pushed up
on the lever and it went to neutral!! Took a second, and without touching
anything, it went to 3rd and gave me a bit of a jolt.

I never touched the lever after the initial shift and looked to make sure I
hadn't gone to neutral myself by accident.

I continued manually shifting all the way home and didn't have another
problem. Normally, after this area I was in, I use "D" for the remainder
of the highway trip, but I wanted to see if I could reproduce it.

When I got home, I checked the tranny fluid and it was fine.

Hyundaitech (or anyone else for that matter), any ideas? Should I just
take it in to check for a code, or wait to see if it was a fluke?
