Any help would be appreciated.

It shouldn't. Take it back to the dealer. It's still under warranty.

thanks a lot, i just wanna know what is that!

Recall or plain old TSB for (same procedure for either)..

Reprogram PCM with #184 and TCM with #185 as a package..

Been doing this since first of last year for 2009/2010 4 cylinder car

V6 has an engine upgrade that might have trans stuff buried in it too..

Thank you for your reply.

Sonata 2010 2.4 L 4-cylinder.

i don't understand the PCM-184 and TCM-185 is a firmware upgrade? is PCM-184 and TCM-185 will fix it?

Thanks Again.

184 -- 09/10MY NFA FL 2.4 SHIFT FEELING IMPROVEMENT - ECM

185 -- 09/10MY NFA FL 2.4 SHIFT FEELING IMPROVEMENT - TCM

If the programs not done, have the car good and hot, then make absolutely sure they clear the adaptive learn for the trans.. then go out and restart the initail adaptive learn while ATF good-n-hot

thanks but, I really don't understand! look like you speak in morse code! i just want to know what causes this strong shake!

thanks again
