Transmission knocking

[Ceazerleo]

Hello friends. My 2018 Wrangler Sahara knocks when i start the egnition. The dealer told me that this is "normal" but im not buying it. I am also having some knocking coming from what I felt like was the tramsission. I took my Wrangler in to the dealership due to concern and they checked it out and confirmed that it was coming from the transmission. They said it was "normal" again and i just dont feel comfortable with that. They confirmed my complaint which is " vehicle had an intermittent slight knocking noise when the vehicle performs a 4-3 shift. Noise was coming from the center of the vehicle. Lifted the vehicle and checked for loose parts and leaks but found none, check for flash updates but found none. test drive another like Jeep Wrangler and found it made the same noise on the 4-3 shift. Noises coming from the transmission, the noise is caused from the internal clutch C engaging and clutch D disengaging. this causes free play in the driveline, when clutch C and D are completely done with the movement the noise is created"

Basically when slowing down the vehicle transmission knocks just before shifting from 4th to 3rd gear. (auto transmission - 8 speed)
Is anyone else having this issue and can anyone provide guidance? Any feedback is much appreciated

I have this same problem on my 2019. Seems like it does it when slowing down to stop or when I have slowed to under 10mph and then accelerated again as if it is locking back into gear. I took it to the dealer and they claim they couldn't duplicate the problem. I can't believe this is normal. I have never had a car make these noises without something being wrong.

You’ve driven too many cars and not enough Jeeps then. You hear noises.

I just don't want to have a transmission failure the day after my warranty expires.

Drive it hard then and try to break it within 60k miles.

I also fear my transmission failing after warranty. These concerning sounds have killed my confidence in the vehicle.

If you drive it long enough, of course it will fail. All things do.

That’s not bad. We regularly see near 400k on them.
