2026 AMG GLE 63 S — looking for others with similar experience
I had consistent harsh downshifts (3→2 and 9→8) in Comfort mode from delivery. The dealer diagnosed fault P089300 (“multiple gears engaged simultaneously”) and replaced the valve body/controller.
During inspection, there was visible metallic debris on the magnetic filter (not excessive per dealer, minimal sludge in the pan). Required multiple adaptation attempts and flushes before passing, now shifting correctly.
Curious if anyone has had a similar valve body failure with debris present — and specifically whether the repair fully resolved things long-term or if any issues developed later.

I would never let a dealership while doing warranty work define "fixed". With out question "good enough" and "tests good" are not the same as a good solid repair.

However, debris is a problem.

mine also does this. Dealer told me it was “normal” I don’t find it normal. I’m going to go to another dealer.

My GLE 63 had similar issues. I took it to the dealer 2 weeks ago with 1500 miles on it. They told me it needs a new valve body. Current ETA is mid July. They told me to drive it home, and wouldn't let me keep a loaner. I called 2 other MB dealers, and they both told me not to drive it. I would point out that the told me if there are metal shavings in the filter/oil, they will replace the transmission. @AndyA24365 You may want to ask them about this.
I am now without my brand new $145K car, waiting for a part, and in the back of my mind I am wondering what long term damage may come out of this.
I have a case open with MB, but they won't do anything until after the car has been fixed. Pretty ridicules.
