Glk350 transmission
So, you're calling all these shops and telling them it's the converter???
Not a good idea ... never make a suggestion, because they will jump all over the worse-case repair.
Any possible issue(s) analysis can only be done IN PERSON. Over the phone and you'll get all sorts of possibilities.
We always start with the simplest and least expensive possible fix. For example, a fluid change - quick and cheap.
My experience with owning and DIY repairs on all types of vehicles for over 40 years, I've never had a bad converter.
Not saying it isn't your issue for sure, but I'd be traveling other paths first.
Heck, my wife's E320 with over 300,000 miles (330k?) has never shown signs of a bad converter.
The major things I've done to that E320 is a new radiator, engine / tranny mounts, and brake pads.
Her 2014 GLK gas, with 93,000 miles - nothing except fluid changes and front brake pads / rotors.
Moisture in the tranny fluid? Have you checked the fluid for its appearance or for contamination?
Another thing to consider about the 4Matic ... it's 4-wheel drive, and is known for having issues with the front shaft /etc.
Have you considered that?
It's all speculation until you get a definitive analysis.
EDIT: also, are you getting any codes? there are torque converter codes that might be thrown. There's probably 10 or so codes.
Some signs of a bad torque converter | tranny:
Loss of acceleration
Slipping between gears
Refuses to shift
Transmission or engine overheating
Transmission fluid leak
