Software Update Available Which May Correct Transmission Issues on Kia Amanti

Problem Description and Possible Solution

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.
perodic lurching of car. Vibrates and excelerates forward.
When I switch on cruise control engine makes all types of weird noises and car vibrates all over. If I turn off cruise vibration & noise stop.
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.
resistance getting to shift from park to drive first start of day. then works fine.No check engine light on. take to mechanic, mechanic says can not find anything wrong. stuck at local grocery store! will not go into gear. all gears except drive. show on dash & shifting. tow to shop. tow driver delivers and says now all gears are working correctly.????
very hard downshift from 5-4 at times shakes entire car
Check engine light comes on and off half the time...
Would not shift from second to third then fourth to fifth gear at 3,000 rpm. Used sport shift to get through day. Car at dealership now being diagnosed.
