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.

I am the person in Report #2 The dealeship determined that the accelerator sensor needed to be replaced and was causing the shifting problem. I hope they are right. Repair cost $440.

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.

Car jerks while in drive right about when it's going to shift into fourth. After that, using the slap shifter indicates I only have 2 & 3 gears. Stop, shut the car off, remove key and then restart and problem is gone. Occurring more often almost at same exact location every morning.
