where do I get the software update for my 2005 kia spectra auto. transmissiom

What is your question?

car goes into 4th gear hard when I go 30-40 mph you feel the shift. If I drive slowly and increase speed slowly there's very little shift that I feel. I went to a k Kia dealership in Newburgh n.y.and they said they knew nothing about a software update. So if possible can you let me know where I can go or how I can get the update. And I'll try it myself. I have approx. 130,000 miles.on the car

How long has your 2005 Kia Spectra had this problem?

about a month
