2014 E Class Needs New Transmission?
So as I was driving yesterday my car would not move once I came to a stop light. The car was still on but when i pressed the gas it wouldn't move nor would it move in reverse. The car only drove in neutral for me to get to the side of the road for it to be towed. Note the car was purchased from Mercedes years ago and has always been maintained there and no lights or anything came on or have been on. Once towed to Mercedes I was told that the car would need a new transmission and I was quoted around $10,000 for them to install it. Now to me this price seems quite excessive, but also for the car to need a new transmission at 90k miles, is this normal? What are your thoughts? Has anyone else had this issue? Reading other posts I've read somewhat similar experiences but haven't seen anyone needing an entire transmission. Thanks!

Call some independent shops and get quotes. I'm willing to bet you could easily cut that price in half. In my experience, most dealerships will want to simply replace the transmission with a brand new one, which is rarely the most cost-effective route, even considering the warranty that comes with it. Heck, it may not even require a full rebuild!
Better yet, call corporate. Politely explain your situation and see what sort of goodwill they can offer. It's below 100k miles so they will probably at least offer you a discount, if not cover the entire cost. It never hurts to ask. Have your maintenance records handy. Showing that you've done all of the maintenance at the dealership will help.
Good luck and let us know how it goes!

Mercedes dealers in general do not fix anything. They only change components. This probably comes from Mercedes Head office in Germany for warranty work as they may want defective part back for inspection. Sad part of this is that the dealers keep doing the exact same thing for cars outside warranty.
Ask the dealer shop or Indy shop to diagnose the problem and pay for this service. If they can tell you what is wrong I guarantee it is not the complete failure of the gear box. Could be just a simple sensor that went bad.

Yeah, ask them for the specific transmission error codes it has. You could also ask them to have a master level service tech work on it. Also a used transmission from a junkyard is about $1500 and labor at most indy garages are in the $1000 range to remove and replace a transmission. So even if it's really the transmission, you can get it done for much less.

90k miles seems very low for your transmission to be bad already, unless you truly beat the hell out of the car. I'm at 110k and now I'm worried mine's going to go.

I was planning on putting a mild tune on mine, but this has me re-thinking that... I hope you can get it repaired for less than quoted, you're like I'm going to sink a third of the car's value into this repair??
Good luck with this...

This actually isn't unusual assuming it's because of defects in the valve body and conductor plate. There was a class action lawsuit against Mercedes for their 722.9 7G-Tronic transmissions, not sure what became of it or if it's still going. I'm assuming you have a 722.9 transmission

Hi guys,
I believe my car is affected by 722.9 transmission issues as well (‘14 E550 w/ only 44k miles). Fortunately, no limp mode or anything catastrophic, but enough jarring shifts to create cause for concern. I’ve raised this issue with my MB dealership. They documented what I was experiencing and took a road test with me. We weren’t able to reproduce the *really* bad shifts but still demonstrated less than butter smooth shifts.
Whoever is interested in this issue should check out PeterUbers’s threads on this forum - very informative.
My question is, without getting to limp mode or worse, how are people getting MB to address a clear issue wit this transmission? I’m still under CPO warranty and want this fixed before it’s up.

Thank you so much!!! I contacted corporate and as a goodwill gesture they are going to cover a big portion since the car has always been serviced at Mercedes and it’s going to be $3,900 out the door instead of $10,000

That's great news, glad to hear it! That's a much easier pill to swallow. I'd still get a second opinion and quote from an independent to verify it does indeed need to be rebuilt. Mercedes may offer a better warranty, though, if you go through them.

Here in NJ or NY dealers were not able to reproduce, the vehicle acts as it came out of the assembly line just now.
Also, every morning, from my home to leasing office/gates, I have that jerk shifting to gear 3. Some times it jerks shifting to gear 5 as well.
I tried video recording it, but it won't prove anything for the dealer as they have to reproduce it themselves to log it as a warranty issue.
PS. My tranny was rebuilt to replace K1-clutch pack for the same reason in 2017 at 47k miles (under factory warranty at that time).
BTW, I tried looking for threads started by PeterUbers’s, but I couldn't find the one referring to this. (There was one regarding the clutch adaptation).
