Software Update Available Which May Correct Transmission Issues on Kia Amanti

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.

transmisson will not shift right. It jump when trying to shift and jerks the car. We put a used 2004 transmission in it and it still does the same thing.

corrosion on the connectors on the tail lights and harness and shorted out factory amplifier for stereo cause of the corrosion would be water leaking in to trunk area by way of tail lights seal ..stereo appears to be on but no sound comes through the speakers
I bought the car used, 2 weeks after I got it the light went in. Dealer said the code was the intake valve sensor. It was replaced and the light was still on. They believe it needs an update. Now the transmission is having issues. Takes a while to go in reverse, if not warmed up, and jerks in drive if it's not warmed up. Also, the a/c has gone out and when we tried to charge it the gauge read that it was overcharged before we even got any coolant in it.
