Torque converter replacement cost

Lately I have started feeling slips on highway which turned out to be from torque converter per dealer diagnosis. Dealer quotes 5k to replace it, calling it as "CVT-Torque converter" in the quote. Last time when it was replaced in warranty 4 years ago I remember bill was generated for around 2k even though I didn't pay anything at that time. Does this sound right ? Vehicle is 2015 E400. Thank you in advance for your responses.

CVT?
What is CVT?

And why so many TC?
In my life I have never myself or known anyone who had to replace a TC unless they were getting a new or rebuilt tranny.

very odd diagnosis

I thought the same originally.... this does sound like busy work.

last time for free but now again for profit. TC is not a normal-wear service item.

The old tranny has been around long enough that pro should be able to call the shots correctly.

Get yourself a second opinion about your issue, not TC...

Thank you @ygmn and @CaliBenzDriver for the replies. Before switching to Mercedes, I never paid attention or learned about TC. I do feel it struggle ( or may be slipping ) on highway speeds when I give acceleration. So the issue is there and may damage the transmission if not addressed soon is my fear.

This tranny was also used in Dodge cars so searching them as well can let you see more....
