What is the Lifetime of 7G Trans. on 2006 Mercedes-Benz E350

I have a Mercedes E 280 year 2006 with 7G Trans. Suddenly the car engine was shut off while driving. The car is inspected by the dealer And advised that the transmission is completely damaged and require replacement. Is it possible that the transmission is completely damaged without any sign and it was working fine without any jerking till the moment of failure? Is the above damage related to manufacturers defect as the 7G transmission is new to Mercedes only fixed on E280 starting in 2006.

We don't have failure rate data for these transmissions, but I looked the technical service bulletins (TSB) for this transmission and there are about 10 of them, so that tells me there have been quite a few issues with it. As long as the dealer looked at any related TSB and exhausted all other possibilities, then it probably needs a new transmission.

Thanks for the reply. Is it possible to have copy or access to the 10 TSB mentioned in the answer.
