Hello. Returning forum member here after 10 years away from Benz.

I spec’d out / ordered a 2021 GLE53 that was delivered 7 months ago. Since I brought it home I have noticed a slight transmission thump /thud when slowing down to a stop sign or red light (always when in Comfort- automatic). Looking at the HUD it is when the car downshifts from 3rd to 2nd gear. After about 30 days I asked the dealer about it and they said the car is learning my driving style and give it 1,000 miles (ummm ok?). Car now has 7k on it and continues to have same issue so I took it in to be looked at. Service technician found metal shavings in transmission, sent pictures to engineering team in Germany, and local dealer was told a new transmission and torque converter were being shipped to be installed next week. Has anyone else had this issue? Hoping this fixes the issue. Comments welcome

Haven't had any issues. Only have 850 miles on mine though. Will be keeping a look out for those symptoms.

They put in a new transmission and torque converter....no issues so far.

Are you allowing the auto start/stop silliness to remain on when you operate the vehicle? (I know it should operate fine with it; let's not plow this field, but I'm curious.)

Jeffer09

I turn it off as soon as I start the car.

coachhomer

how do you disable?

Troubling. I hope I don’t have the same.

I thought I’d do the same with mine, since every vehicle I’d driven with S/S before my GLE53 were rubbish, but you know what? On the 48V vehicles, the S/S is so smooth that it doesn’t bother me.
On my wife’s ‘21 GLE350, totally different story. She turns if off every time she starts the vehicle, as the transition is really noticeable and it’s always lunging when starting off/on to the point of being a nuisance.

Don’t worry. Almost 10k on mine (coupe, but same engine/tranny/tc). Zero issues. Same for other folks on this forum.

I also have exactly the same problem, the car is 2021, the master has so far calibrated the gearbox and the kicks have become less noticeable but still remain, the author, give me your contacts, I want to write to you
GLE 53 Coupe 2021

Man, this thing just does not shift well. Mine hesitates and hunts on upshifts and clunks on downshifts.

I’m just thinking out loud here, but having owned a 2020 BMW X5 M50i with a ZF transmission that shifted invisibility and like butter, there must have been some convincingly eager but overall dumb engineer at MB that said I can build us a transmission and save MB $X dollars. All I can say is this, it wasn’t worth it because this transmission is garbage.

MB transmissions are not good. It's that simple.

I have a 2023 GLE53 and it's doing exactly the same thing with the trans thump/thud when slowing down and when accelerating in traffic around 10mph.

Custom coding/programming and will probably void your warranty

So just push the button every time you get in the car

I would ask them to reset your transmission adaptation module if it hasn't been performed yet.
