Using Xentry to smooth 9G transmission
I recently did a 4 wheel drive service on my 222.
After the trans oil change it was still shifting very clunky on 4-5 and 3-2.
I reset the trans in Xentry, and man I have to say, it's butter smooth.
Just a PSA.

W222 400D 4-matic
My dealer did just the oposite. Didnt reset those values after an gearbox-oilchange. When i got the car back it shifted even worse than before 
Their answer was it wasnt alowed by MB here in Holland. Sure..
Went to a indy wich told me thats BS and even manditory! He performed the "reset" and since then it started shifting better every day. Day after day. Now after some 40k miles it shifts like new.

Instead of the simple reset, you should run the adaptation tasks for each gear change. A lazy reset is not much better than no reset at all. Most likely the transmission adapts slowly to the same point in either case. Proper adaptation is just time consuming which is probably why the indy did not suggest that any more than the dealer.

The reason I sold my W222 and switched to BMW recently is exactly this reason. Mercedes has lost a lot of my respect due to their jerky transmissions in the last 10 years. It is a shame that they still could not dial in a perfect smooth transmission. BMW transmissions are 10 levels above W222’s transmission. Even though I am on the market again shopping for a W222 once again, but I am still super concerned because I had a very bad experience with my previous W222 and took for ever to fix it but still not as near as good BMW feeling. I think it is hit or miss. I know not every car like that, but this seems to be a common and and well documented problem. Probably the only solution is to just design the 7G or 9G transmission from scratch instead of trying to update it again and again and again. It’s a shame.

Did you realize that I am actually the same person who posted that originally :P lol. That is my thread/post. So, of course yes. It made it better (smoother). But still my complain overall is that ever after it’s fixed you still feel the transmission is not as smooth as a luxury vehicle should feel.

It took a WHILE, you have to go through all the upshifts and all the downshifts.
I made a free afternoon for this task.
But, I will say, this car is BUTTER, smooth now and I'm loving it.
I'm going to have a Weistec tune put on it soon, so I wanted the trans to be fresh.
The trans seems to adapt more and more as I drive, it actually anticipated 6th gear in one case which was a change.
The 5-4 and 3-2 hard shifts are gone as mainly that was my issue, but overall it's much less 'shifty'

I'm going to have a Weistec tune out on it soon, so I wanted the trans to be fresh.

.... am I in the minority twice? OR is the problem the minority?
One thing for sure, being illustrated in the forum puts it square in the publics face, and hopefully also in the face of MB...

Interesting...My 2017 S500 4-Matic is buttery smooth in all situations, from light acceleration to pedal to the floor.

My S550 has a very rough 5-4 downshift and an occasionally rough 3-2 downshift. I have had the fluid flushed and software updated, but no changes. I really wish it was “buttery smooth.”

I like how the PDF doc characterizes the problem as "caused by the engine changing from overrun to combustion mode" ... I would have said "starting uphill after coasting under light load" or something, but I think this does describe it well.
