Exclamation S63 or CL63 trans in S550

So, my 7G-tronic going out, need a tranny swap. (RWD Base Model)

Option 1: get a used 60K transmission for approx. $2500
Option 2: get an AMG S63 or CL63 trans if its possible...

Anyone done this before? I'm told its a direct fit but the torque converter and conductor plate may have to be swapped in from the original.

Thoughts?

Anyone know what year Tranny I can go up to in a 2007 S550 RWD, would love to put in a 2011 trans if its compatible.

I think I'm going to take that advice... want a new car in a couple years, not worth the trouble.

You may want to inquire about a factory rebuilt trans. I had the 5 speed tranny in my 600 replaced last year and the cost of the factory rebuilt trans was $3800 plus labor. As good as a new one from what I'm told....and then you're not risking a possibly bad trans from an old car.
