Anyone know the solenoid part numbers that need to be replaced?

Could you post the whole TSB that includes the instructions on how to fix the issue or a link with the entire TSB?

Is this a recall that will be done free of charge?

Looks like I escaped this one. They worked out most of the kinks for MY2016.

Can you share this TSB? please

Can't find details of that one but found 2 related on NHTSA recall site. Not for the faint hearted. Here's one:

@Roc those docs (tsb) are old already, i thought in 21-50-003 there is something new about problem with our transmission.

They maybe old, but was also asked about complexity. Those 2 TSBs show no easy backyard fix for anything related to the transmission solenoids, etc., as well as showing location of each of them. Don't know why the 23 July 2021 TSB is not recorded in Hyundai TSB listings or expanded, other than it's an official Hyundai document. It does address one specific complaint, however.

The main problem that not only those two solenoids is the problem, cause all of them working incorrect since the problem was discovered. Thats why im trying to find new information.

Hi Guys, seems only i'm interested to solve this problem, last (by the date) TSB looks like is this one: # 21-AT-018H

To be sure, for those who understand the problem - not only those two solenoids is the problem and near those two, you should replace all of them, look at this video (its in russian but you dont need to understand what he speak), the idea that he shows that another solenoids are opened incorectly.

I hope there is someone out there who has some recent info on this issue. Like, are we on our own or is this covered. I have a 2013 3.8 Sedan. The original trans was replaced under warranty at about 45K miles. It now is doing the same harsh and delayed shifts again. Any info/intel would be appreciated. Thank you

You can write some complaint to Home | NHTSA , and to explain, that replace of transmission doesnt solve the main problem.
Maybe in this case if they will receive some complaints, they will put pressure on the manufacturer.
This transmission is a copy of BMW ZF, but a different in the valve body (where installed solenoids). Honda has the same transmission with better valve body, but they dont have such troubles.

Did anyone find out if this was a going to be a recall or just a TSB bulletin?

Hello guys, new update with the problem of transmission.
Accidentally we found that on Genesis DH, there is a problem with Brake booster, the central membrane is broken in wet (medium) climate (i thinks its a time problem of anywhere).

The main idea that brake booster gain much more air than needed, and the valve isnt closed when needed, as a result, the ECM gain wrong data from the Torque sensor, and thats why we got transmission shocks.
In attachment you will see photos from two different genesis, with ODO km 70k km
