Default Post tranny flush

I had my transmission flush yesterday for the shuddering issue. I have put about 180 miles on the car and two temp cycles.Still a bit of a shudder but not nearly as bad and I noticed my transmission shifting is much more crisp. I'll give it till the weekend but has anybody else had the flush done but the shudder not going away after the temp/mileage period?

When mine had the (at that time what they called the "triple flush") fluid changed, the change was immediate. That was in August of 2017. No issues since. Hoping it works out well for you.

My first 2019 GS Coupe: had the trans flushed a total of 6 times before they finally got the shudder to subside, however I could still feel a slight vibration every time it went to eco-mode. I installed a Range Extender which solved that problem. I got rid of the coupe and got a 2019 GS vert. The range extender is installed, that being said, after I get a few hundred miles on it, I will remove the Range Extender to see it the shudder condition is present in this trans. If it is, I will start the flushing while I still the warranty.

Someone mentioned the other day that as of July 09/19 the requirement for a service test of the trans and shudder present is no longer required. The customer can now just ask for a flush with the updated trans fluid while still under original warranty. It was an amendment to the original SB.
I have been looking for the thread posting but can't find it. Anyone else see it and/or know the thread title? It also had a link to the SB.
thanks - tom

I remember reading that as well. I'll give it till Monday and if it still has the shudder I'll call my dealer. I noticed on my invoice that they used 24 quarts of fluid so I am assuming that was a triple?

Cousin had shudder and took it in and they flushed it and it took 24 qts as well. No questions and no test but he had to take it to a second dealer to get it done.
