I agree if you are presenting a car WITH TCC Shudder, but if you present your car to dealer WITHOUT shudder symptoms , there might be a gray area Bulletin correction section talks about car being presented with shudder complaint. I was answering question regarding cars being covered by bulletin WITH OUT symptoms.
I suppose if the trans doesn't shudder, the customer shouldn't be bringing the car in for repair in the first place.
The bulletin says "diagnosis beyond the customer complaint is not required". That's it. So assuming the customer says it has a shudder, the flush hasn't been done before, and fits in the eligibility dates, it should be done. IF the dealer requires diagnosis/verification of a shudder to do the repair, he is not following the TSB. No technicalities, gray areas, or anything else. Besides, they get paid quite well to do this procedure, there's no reason for them to be dicks about it.

Either you are misinterpreting or we're both saying the same thing, only in different ways.

Nope. Just tell them it feels like driving on rumble strips occasionally. TSB says all they need is complaint from customer. Just had mine done( no issues just wanted it done) and Service Manager says GM pays well to do it and he is happy to perform warranty work for GM. I reinstalled by Range when I got home.

I had the triple flush done at my local dealership a couple weeks ago. No charge. Car runs fine now. I was hoping and praying that I would make it home when I noticed the problem. It feels like you are driving over rumble strips. Scary stuff.

Just playing a little detective here.Did you give the range time to clear before your dealer visit?Or maybe you have a great relationship with said dealer and Range was overlooked? A recent thread here with torque tube issue with a range device is perfect timing on my needing a TF now.

I pulled my Soler TC, Range and put back fuse 42 a couple days prior to having the Flush done. I wasn’t consciously think about giving the Range time to clear - just didn’t want any obvious “mods” when I went to dealer. I left my Soler TB on - Soler modified it from an OEM throttle body so unless they pull it off they wouldn’t notice it.
Since I had it in I also had the oil and rear end fluid changed (on my dime), so the dealer performed a profitable service.

My ‘16 z06 is out of warranty and I noticed the shudder twice. Bought it 2 weeks ago and can’t get any history information. I was able to look online and it didn’t show the mag ride update so I have the following services scheduled on my dime next week:
Trans flush
Mag ride update
Add Android Auto
My question is that since the tans flush is $600+ from what I remember, should I do this on my own? Hard to do? I can change my own oil. Hard or expensive to source the correct updated fluids?

For those who have experienced the problem, is it truly this violent?
The simile of "driving over rumble strips" sounds like hyperbole.
I am not questioning others' experience, but having not experienced the problem I am curious as to whether it truly is this dramatic.

Each vehicle is different, my GMC truck? yes it was that bad, I pulled it off the road shut it down and tried it again it was that violent So it’s Not an over statement. I’d imagine some Corvettes are as bad as my truck was. My GS was “definitely” noticeable but fortunately not as bad as my truck though.

That is the exact description I used when explaining the Issue. Some may be less significant.
