Sorry for hurting your feelings John. I had no intention of ruining you day.

You are right, there is a lot of good advise on these forums. And there are a lot of repairs on ML's that can easily be fixed without diagnosis, like window switches, fuel level sensors, filters, aux fans, blah blah blah.

Aawawa, said that her vehicle was already in the shop and they're suggesting a transmission. I was just advising that person to get a proper diagnosis of the trans. Especially before replacement of the entire transmission as stated in the post. The adaptation data is the best and cheapest starting point I can think of before they authorize a complete replacement.
Relax and have a nice day.
