Transmission Control Unit (TCU) Update

[Jonathan Lasich]

Yes I think your right. But your car has the phone charger pad doesn’t it.

Yes, and the 360 camera.

Nice. Did you get the transmission update in Canada.

No I haven't. I had heard rumors that there might be a transmission update to fix this issue (?2019 retrofit?), but when I called my local Kia dealer at the end of August to find out, they told me there were no transmission updates available for the car at that time.

So they made the programming worse for 2019 (reverts to D even sport mode)? When did 2019s come out and when did you get yours? All the way back in August?

I would expect the 2019s to already have the TCU update recently released for the 2018s.

Sorry, let me clarify. The 2019s don't revert back to "D". I was hoping that the 2018s could be reprogrammed similar to the 2019s so that mine would stop doing that.

I have a 2018 . Since December 2017. No 2019 out yet

The rest of ours do not revert if in Sport mode, so there must be some update available to yours if it was a very early build.

 

[Fl stingergt]

Mine is all good holds gears and stays in gear. No problems

I certainly hope so! I actually have a call to the service manager of my local Kia dealer. He's looking into it with his technicians as to whether there is a TSB to address this, but haven't heard back from him yet.

To the guy worried about hitting the red line. If KIA qualified this engine the way they qualify their other engines you have nothing to worry about. I read an article that KIA will run an engine at redline for almost 11 days straight and then run it 10% above red line for another 24 hours. Only if it survives that with minimal wear will they certify it for production. If you bounced off red line for a second, you were 950,399 seconds shy of KIA's standard testing.

That would be me. Thanks for helping me sleep more soundly tonight!

Hahaha, I saw your number and did the math. I think that "Merlin" would be even more pleased to know that you left out the number of seconds for the 10% higher rpm 24 hour period. Leaving you with 950,400 + 86400 - 1 = 1036799 seconds. I am glad that the engine is tested this vigorously! Thanks for sharing this.

 

[St1nger Guy]

Yeah I didn't count the 24 hours above red line because he wasn't running above, just bounced off it. The additional time does look more impressive though, I'll allow it

 

[Marc Collins]

I hope some more people who have had this done will confirm/describe the effects of it on the shift logic...

 

[Crisis]

Nope. As long as you are moving, it stays in manual. As soon as the car comes to a full stop, back to "D". I tried it in all modes (I drive almost exclusively in Sport mode), with the traction control on and off, and with the stability control on and off. Same result every time. Full stop--> back to "D". You have to pull on a paddle to get it back into manual mode. At EVERY stop, you have to hit the paddle before driving off. Hate it!

The rest of ours do not revert if in Sport mode, so there must be some update available to yours if it was a very early build.

My experience has been exactly as described by Jonathan above. Regardless of Drive Mode selected (generally Custom with mostly Sport settings, including transmission for me), the transmission will always revert to D when the car comes to a full stop. I drive using the paddles all the time and would really like to see this corrected in a transmission programming update.

What is your build month/year?

 

[Fl stingergt]

I’m still pissed they did that update to my transmission. It took the sport out of sport mode.

 

[Crisis]

What is your build month/year?

03/18 according to the plate on the door jamb. Not a particularly early build.

My build date is also 03/18.

I looked through this thread and could not find it (maybe I missed it). Marc, you have the updated transmission software if I'm not mistaken. What is the build date of your car?

I'm going to the Kia dealer after work today to get info on any transmission software update on my car. Hopefully, there is!

No, I don't have the updated TCU discussed here. It shows in the dealer's network as for cars with mechanical shifter only (not drive-by-wire). My car is also older (late 2017 build). !! So confusing as to what works how.

For those whose car reverts to D at a stop even in Sport Mode, try clicking off TC beforehand and see if that makes a difference. It should affect some aspects of the transmission programming/operation.
