Mercedes Engine Rebuild

Rebuilding transmission on Mercedes ML350?
I have a 2004 Mercedes ML 350 with ~95K miles on it. A couple of days ago a "Low Range" light came on and yesterday the "Check Engine" light came on. I took it to the dealer for diagnosis this morning and they told me that my transmission is hosed. They are saying that to fully replace the transmission will cost me $14K and to rebuild my existing one will cost $6,400. After initial shock, I've decided to take it for the second opinion. When I informed the dealer that I will pick up the car they told me that they will charge me $500 (!) for putting it back together. After haggling with them back and forth they said that they will rebuid the transmission for $3,200 (50% discount from the original quote). What should I do? Any suggestions? Is it a standard practice to charge for "diagnosis"?
Yes it is standard practice for a diagnosis fee. There are expenses involved for time,light, all that kind of stuff. Ever go into a doctor's office for free? $3200 for a Mercedes rebuild is a bargain. Take it if you are overall comfortable with the dealer.
