Torque Converter issue?
2011 Mercedes Benz C300 4matic 54,000 miles.
During acceleration and while under load, the car shakes quite badly. I took it to the Mercedes dealership and I was told it will need a new torque converter and lock up solenoid, which will cost me about $4000. With this having so little miles, whats the likely hood that I will not have to replace the torque converter? Will replacing the lock up solenoid fix the issue?
I just purchased this vehicle about 3 months ago and I am not trying to spend 4grand.
Thanks,
Mike

Guys, anything helps. Above is a picture of the diagnosis from the technician. From what I understand about torque converters, I thought the lock up clutch is supposed to engage under high speeds. The shaking occurs during all speeds all gears. So i am a little sceptical of the diagnosis.

That is hefty indeed....
There has been various transmission issues on 7g-tronic with 4matic. Cannot really help you...
Having said that, do you know when was the last time transmission fluid was flushed? Transmission fluid should be flushed every 35,000 miles.

I do not know that. However, I do know that the previous owner had some service plan. So I am assuming that it was performed.
I did notice another issue. While in reverse and turning (parallel parking) I am hearing a clunking sound. I’m thinking it’s related, but I could be wrong.
Any thoughts?

W204 owners don't like talking about transmission issues, unless you have some idiot come in and tell you about when it should/should've been serviced, cause that really helps after the fact :/
The bearings in my torque converter need to be replaced also, my symptoms are noise though so far. I've gone to a fairly reputable indie shop in Toronto Canada and they said the bearings need to be replaced which would cost me $3100 CAD all in to get it done, I haven't done anything yet though.

Very possible. Check for fluid contamination, but that's not the only cause of TCC issues. I've seen them fail in fairly low mileage cars for no apparent reason. I did a valve body on one and it didn't fix it, ended up doing the converter anyway.
Yes the part is expensive, but the labor shouldn't be too bad. Look for a rebuilt converter, i'm sure they are out there by now. This repair should be under $2k at an independent shop.

2011 MB C300 Torque Converter Failure 108k miles
I bot this car last week, drove it around first but not get into a situation where this problem revealed itself, so now I am screwed.
Driving down the highway, steady speed, I gently press accelerator to pass and the car start rumbling. Does so every time.
I cycled through the gears, and it only happens in 6th gear.
I described to a mercedes mechanic and he said the TC needs to be replaced.
Does Bosch make this product or any other quality manufacturers, dont want to pay up for OEM part.

Normally I would say I would grab one off rockauto but they don't have any listed, which is odd. I'd have to check what is available, but really any good rebuild will be just fine, they are pretty common pieces, there are tens of thousands of cars on the road with that transmission in it, I wouldn't pay more than $300 or so for one, def not the crazy oem price.

I'd have to look up warranty times but I believe labor should be 6-7 hours max to replace the converter, and I would have no issue with any independent shop that could do it, it's not a special car to work on in that regard. I'm fairly certain there is a reset of the TCC learning that should be done via Xentry/SDS when you replace the converter, but beyond that anyone can do the install for you.
