6th Gear Shudder/Vibration

6th Gear Shudder/Vibration
Curious if anyone is experiencing this...2019 Base Cayenne that is vibrating similar to when a front wheel is out of balance, it's mild but noticeable (not like running over those textured strips on the sides of the road), but very noticeable on the wheel and even dashboard. Happens ONLY in six gear whether in 'individual', 'sport', or manual shifting. When you bump up to 7th gear, it smooths right out...drop down to fifth, same thing. Especially noticeable in 'sport' mode since the tranny tends to hang in 6th gear when traveling 40-60 mph until one reaches highway speeds. Plan on bringing it in next week and thought it wise to check if anyone has same issue or may have an idea what's going on (perhaps a software problem in the tranny)?

If you were to drive in 5th from 40-60, does it happen? if so its a tire balancing issue.

Thanks for replies, the reason I don't think its a balance issue is due to it happening only in six gear, at a variety of speeds. I can be driving at 55, roughly 2000 rpm I think, and an upshift or downshift will stop it immediately regardless if I remain at that steady speed or speed up or slow down..doesn't seem to be related to speed or rpm. Feels similar to torque converter shudder or the vibration one gets when there's a tranny problem (no clunking or unusual noise). I'll report back after car is in the shop, 24K on the OD.

Does it do it under acceleration and coasting? Get into 6th gear, manual mode, take your foot off the accelerator, leaving it in 6th. What happens?
AC on or off?
AC on or off?

I have felt the same sensation in my Cayenne S also! Feels like a shuddering or vibration not the tires out of balance. Maybe its when the car coasts and is disengages the gears from the
transmission i don't know but have felt the same sensation too! curious what dealer has to say about it! Keep us posted! Thanks..

Silver, when I get off the throttle and glide, the same vibration remains as the car slows...also tried throwing into neutral from six and vibe stops immediately. And as I mentioned, 5th or 7th smooths everything right out. Tested it in "Auto" mode with AC on, I'll have to try with no AC. I don't believe wheel balance has anything to do with it. I didn't mention that the vibration is quite noticeable in the seat as well (6th gear for massage maybe).

I would suggest that your problem is in the gearing, possibly a race with chatter marks, or a defective bearing. Your car must go in to be fully and properly diagnosed before the problem becomes serious or causes a complete transmission failure. Do not waste time. Get it in asap. I hope you prove me wrong.

I feel the same thing but at higher speeds on the highway. I complained to the dealer and they misunderstood me and started to look for rattles inside the vehicle instead of looking for this light vibration that I feel like if the rear tires were out of balance.
They even said that once they removed couple crates I had in the trunk the rattle stopped, of course this wasn't the problem but I need to go back there after my next road trip.
