I just got my '17 5 days ago and I noticed that clunk immediately. The dealer said it was the braking mitigation charging the brakes when you're braking close to a car in front. Makes sense, I payed attention after that and it doesn't clunk when there's no one in front of me. At least I don't notice it. Am I wrong about that?

Not sure we are talking about the same thing...I brought mine in a few weeks ago for the TSB application and the "clunk" is gone.

There's also a bit of slop in the driveline which can occasionally cause a clunk if you quickly let off the gas. I think it's just the nature of the beast.

Re: '17 transmission clunk

Mine clunks in auto from 6-5 when slowing down, in manual mode it will clunk from 6-5 and 5-4 as well. Sports mode makes while downshifting with no throttle or braking clunk through 6-5-4-3. I've noticed if accelerating when downshifting with the paddles it will not clunk, it is only an issue when foot is on the brake and slowing down.

Sometimes accelerating from a stop in 1 you will hear a clunk as it takes off.

I'll be doing the flash tomorrow, hopefully it helps.

I got mine to the latest software, still the same, must be driveline. I got a fix for it, just install Borla Atak or S-Type exhaust and you'll forget about the clunking.

Going borla atak, even so the clunk can be felt.

Some people here are saying that the flash fixed the clunk. So it makes me feel if it doesn't fix mine then there is something wrong

Flash fixed mine...but I just turned 6k miles and it is starting to act up again. I read in one of the topics that the trans does a hard reset at 6k miles...or something...I am wondering if it has something to do with it....
I will absolutely confirm that mine had a clunk .or a slight forward thrust..just as the vehicle came to a stop...and the frequency definitely increased as time went on. Dealer did a refresh and it vanished for awhile...I definitely think it is in the programming.

Re: '17 transmission clunk

Flash done, soon as I drove it away from the dealer and stopped it clunked from 6-5, just as loud as before it got flashed, now it seems to be getting better where you can still feel and hear the clunk but it is not loud. They told me they did not to a transmissions adaptive relearn as it could cause more problems, they only do that when there are actual parts changed. True or not?

Isn't a transmissions adaptive relearn just an unplug of the battery?

The clunk I get from accelerating from a complete stop in 1 is gone though.

The dealer can apply the adaptive relearn at any time if the customer complains of harsh shifting. It's usually the first thing they do, followed by replacing the valve body, followed by replacing the transmission. The adaptive relearn is a software reset procedure... it's a little more involved than simply disconnecting the battery.

You may notice improved shifting after the relearn or it could take a few hundred miles of driving. You have to give it that chance. I had harsh 3-4 upshifts and 2-1 downshifts on my 14. The relearn immediately solved the harsh upshift but it took about 400 miles of driving before the harsh downshifts disappeared. Never had any more problems after that.

If your dealer told you the adaptive relearn "could cause more problems" then he's blowing smoke up your rear.

Re: '17 transmission clunk

Its the FCA trans programming. Not so sure why some are worse than others but there is some unneccesarily harsh off throttle downshift programming in there.
Now that we have trans tuning software, it is easily corrected and other tweaks can be done too.
Fantastic trans when tuned...but sorry that doesn't really help the guys with stock vehicles.
