Just got a notice on Recall 15389....anyone else?

Nothing for me yet. What's the subject of the recall?

I searched for recalls for my vehicle and didn't come up with anything.

Click me.

I posted this in the 8 speed transmission flash thread as well.

I had been reading about this recall on the GM-trucks forum and decided to check if my yukon applied. I went to GMC center, created login, etc...and searched the recalls for my VIN. The only one that popped up was the below recall:

RECALL #2015216 PROPSHAFT U-JOINT RETAINER BOLTS LOSS OF INDEX (PARTS - NEED TO ORDER)

So this morning, I called the Dealer and got the ball rolling for them to order parts for the above recall. As he was checking, he noted that there was one more recall, #15389:

RECALL #2015389 TORQUE CONVERTER CLUTCH (TCC) SHUDDER (NO PARTS)


This is strange because recall 15389 didn't show up when I logged into my GMC owner center account.

I suggest you guys call your dealer and have him check. It looks like they have more up to date real time information vs. the information I saw in my GMC owner center account.

Did they have information on a fix for the TCC shudder?

I posted this under the 8 speed transmission software flash
"I had the Torque Converter update done, the U Joint was released 2 days after I had mine in for service. I would say the Clunk is less noticeable now. Im out of town for the next week, will keep listening. "

UPDATE:
Left ours at a local dealer on Friday and listed out all of my issues.
Open Recall on U Joint
Clunk at stop start
25-35 mph trans doenst know what to do.

Received a call from my service rep today.
U joint Recall seems to have fixed clunk.
the other part...he said..."I don't have the full data, but, I did call our sister cady dealership and they had 2 escalades with the same issue. Your new transmission is on its way and will be here wed/thurs and you will have your car back on Friday.
I told him to make sure the transmission had a build date of after 3/15 and he said he was aware of the changes post that date and didnt know the build date.
