At least I have that consolation that I'll happily take my $77k back, but then I'll have to decide what to do with it. [/QUOTE]

7K more and you can get a TESLA. have you driven that?

no drivers assist features though.

SnakeDoctor

That is exactly what I experience. I noticed it the first day I drove the car home from the dealership. You are right, it's not 100% of the time, but it was often enough that some of drivers noticed it. I haven't noticed it happening as much over the last coupe of days. Maybe once or twice in ...30-40 miles worth of driving.

My previous E350's all have this issue (2013 Palladium Silver and Diamond White, 2014 Steel Grey and current Diamond White). As K-A said it's the 7G and it's not all occurences but if you play around with it enough you'll notice. I, for one, do not care much for the shifts to go to the dealer and tell them to "fix" an issue that I believe they cannot...

PeterUbers

qtip --

there is a distinct difference in how my palladium 2014 was driving after the clutchpack replacement compared to how it was driving before -- I mean it was slamming into gears. not normal and to the point where the master tech and service advisor said "this is definitely not right"

All they had to do was say "nope, that's normal for 7g-tronic transmissions..."

They knew and know on this obsidian E550 that it's a real problem, and my CLS550 drives perfect -- get me to that point with my E550 and I'll drop this issue.

yes, they can fix the problem I have, perhaps not the problems that you've had (as they may have been more subtle and more or a nuisance than an actual problem like mine)

regards

PeterUbers

Maybe it's time to drive a Tesla... I can live without the driver's assist features... and perfectly smooth single gear transmission, right? 0 to 10,000 rpms .. butter smooth, instant torque

MBUSA should get all 2014 models under "amber light" and fix them all if any complaint. This is absolutely ridiculous problem to have on a car that carries Mercedes Benz on it. The brand name used to mean you can drive the car as long as you want to with normal wear and tear parts replacement. Now it seems you need to replace the tranny to drive it.


All car makers make mistakes, which is understandable but as much as it seems the car buyers must go thru to get the manufacturing defects fixed is not right. I'm having serious second thoughts to stay with MB for my next car.


If the car seller or maker fixes the warranty issues under warranty without fight is fine but it seems with these big issues MB makes it a big fight. NOT FOR ME, PERIOD!!

PeterUbers

"The Best or Nothing," Arrie ... I'm with you!

martinlarose

Good luck with this issue Peter and keep us up to date. Mine is still buttery smooth and trouble free after 23000 kms

BenzV12

Sorry to hear about that tranny problem .MB don't make trannies but that's not excuse for a defected tranny and repeated failure in your replacement car . Mine shifts smoothly

pamiboy

So sorry to hear about your problems, but at least you have some solution figured out.
In my car during the break in period I had some really harsh downshifts 4,3,2 while climbing uphill but I figured out to minimize those by giving more gas and it went away. Now I occasionally have this poor rev matching shift from 4th to 5th up shift but it is not that harsh ( anyway it seems to be getting more and more infrequent). And downshifts are smooth. Thank god.

Mercedes is one of the few manufactures that actually does make their own transmissions. Most are joint ventures between the domestics or sourced from ZF.

Mercedes transmissions have been some of the most consistently reliable and durable automatic transmissions since autos became a thing.

They have also always been a little more finicky than one that will crap the bed at 35K miles. The 4-speed in 70/80/90s S-Classes were known for being a bit clunky. The 5 speeds were pretty damn close to perfection and the 7-speeds, particularly on high compression engine models, seem to be a little clunky with downshifts.

fintail

If you want to see clunky, see the unit in my fintail, which has MBs first in-house automatic (previous units were Borg-Warner, I think). It doesn't have a torque converter, so shifts can randomly be slippy or clunky - 3-2 is most common for that. Apparently they did it from new, and have a very low failure rate. Eventually it becomes just another quirk of the car, and it fades into the background.

My old W126 300SE had a new transmission under warranty at 100K miles (car was still 4 years old, maybe some goodwill there) - but I don't know if it was a service issue or just a flaw.

The Bluetec is only at about 10K miles, and most shifts are perfectly smooth, but I think every blue moon I get a jerky one.

PeterUbers

Thanks for your ongoing support guys, update today:

Svc manager called and said this one shifts harder and more frequently than the last one! Offered me the cls550 4matic to me as a trade since it shifts smooth but I don't dig the cls550.

Said they're prioritizing my case at the svc bay, and understand that if I don't get it fixed this week I want all my cash back and they won't fight me on this. They seem confident that they can get this fixed but aren't being specific on what the fix will be, will it be the same rebuild as before...

Will update u all as I know, thanks for listening

instantfob

"The Best or Nothing ..."

Take the S550 instead

axhoaxho

Sounds like a nice offer... might keep it open for consideration.

SnakeDoctor

If the CLS550 is fully loaded...why not? Be done with the headache. I like the E coupe better too though

sorry, edit. I like the E coupe AND sedan better too.

chrisvr6

my 2010 e350 rwd gets some kind of bug every once in awhile where it upshifts 4-5 really rough. It magically disappears too. Seems like its not mechanical but more software related. Crazy stuff.

PeterUbers

Chris, likely a similar problem

The cls is not loaded, no parktronic or distronic or pano like my e. No split fold rear seats or rear extra side air bags like mine. The car has 3800 miles on it and is a blue gray that I don't like and stock 18s that I feel are not as nice as my e

Would rather have my cash back
But good points by everyone

SnakeDoctor

Well for what its worth, my car seems to no longer suffer from the hitch. If it is doing it, I certainly don't notice it as much.

PeterUbers

How many miles on yur car now? Funny thing is my car would be fine for a week and then the nasty clunk would rear it's ugly head, then it would be constant for a few days then go back to being intermittent. Nothing makes sense

Fwiw, I'm glad yur car is either better or you aren't noticing it, ignorance is bliss ... Just hope it's good for the long run or as long as you intend to keep it

PeterUbers

Motortrend or car and driver mentioned the clunky trans in the 2014 s550 review....

usamuscle

Hey peter I have the same on my 14. Funny that once in a while I will know right away and look down and see its in 4th. I say to my self ,, yepppp and small chuckle. Not sure when I'll let stealer ship look at it, after 2 different dealers couldn't fix my front seat belt noise. some real bright ones.

Vernon Mather

You shouldn't have shifting problems at such low mileages so it can't be a wear problem. This is normally associated with computer software and this relates to faulty ECU's and/or dry joints. Sometimes you have a problem with tooling and component tolerances are compromised. MERCEDES; WE never have this problem! Yeah right! But don't despair, if it is wear related you have in the USA an incredible additive called Dr Tranny Instant Shudder Fix. By-pass you Stealership (this once) and get a transmission shop to put in this Tranny Fix and you will be amazed at the results. We have had an almost 100% success rate here in South Africa on ZF 'boxes and I can't see much difference in the two transmissions re: operating tolerances and lubricant qualities. Give it a shot.

kash2014

I'm pretty sure it would void the warranty, when you pay that much money, its MB's problem.

SnakeDoctor

Little over 350 or something around there. I'll keep you posted, but so far so good.
