Software Update Available Which May Correct Transmission Issues on Kia Sorento

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.

Sluggish movement when you shift to drive. I think it start with the 3rd gear and the check light comes on.
going out of park to another gear it shifts real hard.and will only go 5 mph. cut it off and restart it sevsreal times. and then it will drive as normal REALLY REALLY AGGERVATING!!!!!!!! PLEASE FIGURE THIS ONE OUT KIA PLEASE!!!
Sometimes when reversing and brakes are applied the vehicle disengages the reverse gear even when the gas pedal is depressed the vehicle will not move backwards. I need to turn off the ignition and restart the car in park to put the vehicle back in reverse to move back further. On occasions when I happen to have reverse far enough out of the garage and braked and and reverse gear has disengaged. And I am able to drive forward. The vehicle pulls off in 3rd gear and will never go higher than 5th gear. No matter how many stops I do. The transmission never shifts to first gear. Not until the I stop the vehicle turn off the ignition and restart the car in park, will it reset and shift from first gear.
This vehicle has been in the shop more than 8 times for the same transmision issue starting around 20k miles It first started when doing a 3 point turn it would never engage reverse gear and also required the vehicle to be turned off and restarted in P to then engage R to complete the 3 point turn. This is beside the brake failure I had when the vehicle had less the 200 miles. The rear passenger side brake cylinder leaked out all the fluid and then at around 20K miles the master cylinder was replaced because the brake pedal would go to the floor. All I get from KIA is " We have not been able to duplicate the problem"
The transmission issues seem to be a common problem with these Kia Sorento's Has anyone been able to get their problem fixed or are we all still listening to the the service man saying " We have not been able to duplicate the reported problem" I sometimes think that KIA is just waiting for my 100K warranty to run out before they just happen to find the problem.
transmission "clunks" into gear between 40-50 mph. was like this when I bought it new, been in 3 times with "unable to duplicate"
From park to reverse or drive it shift after a second or so rather rough.
Also dowe shifting when slowing down it is rough
Driving down free way car feel like I hit something hard take in to dealer they do transmission update. Problem fixed
When driving 70 mph rpm stays at 4 and when you put the shift to "manually" it's always in fourth gear when driving automatically it just won't chift
just googled and found this article on why the transmission may not be shifting. Intend to have it looked into. Hoping not a big problem
Has been doing this since it was new.. I mention it every time I go in for service.. I have had all the scheduled maintenance done at Kia dealer.. they say it is normal for the car.. I will show this to themm.. I am curious if they say they have the software updte
