Software Update Available Which May Correct Transmission Issues on Kia Rio

Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.

problem details
The check engine light would initially come on at random & now never goes out. While the check engine light is lit, the shifting of the transmission is a "hard shift" if it shifts at all. Sometime the car will not move & then will move in a "bucking" motion. I have not been able to fix the problem as i was told it was my computer that needed to be replaced & i am not able to afford it. But, after reading this it seems i may need to reset the computer

Gets "confused" changing gears before getting stuck in second gear. Engine light comes on. Runs great, but unfortunately, only in second gear:)

Ck. Engine light would come on briefly and go out, after a few months it came on and stayed on so had it check and it showed " Automatic transmission speed sensor" was bad have tried to replace it but no one including Kia seems to have 1 to match it.
