Thank you for the reply from Al!
I sincerely appreciate him taking the time to address our issues and give us an explanation! And thank you to Camaro5 for the opportunity to ask questions to the GM Team!!
I just picked mine up from the shop. This will be the second flush I've received. I spoke to the foreman and he said he thinks that when they did the flush the first time that the ATF bottles looks the same but the manufacturer date had to be past a certain date. He says now they made sure that the date was correct and they used Mobile 1 but did not replace the filter. Says they couldn't duplicate the shudder when it went in, (yet it does it all the time). I was honestly expecting a new torque converter, especially since I've already been through one round of flushing. I explained to him that I was an early production, my production date is 6/2016, so I'm one of the ones that could of had the issue even after the first flush. So I'm keeping my fingers crossed that this fixed it.
