722.9 MCT rebuild

2011 E63; 60k miles. When transmission is warm, juddering when accelerating from a stop in the first few gears. Worse on a hill and also in reverse.
Also noticed that rpm fluctuates a bit when driving and in D mode at a light the car something feels a bit light it wants to go.
Transmisson oil/filter replacement done. Got a bit better. Shift adaptation done and got a bit better.
But often times it still looks like I am driving a stick and don’t know how to.
Indy that only works on MB isn’t convinced a full flush would solve my woes.
$4K for pulling transmission, replace wet clutch pack and one solenoid. I’ll get a second quote but this seems reasonable.
They are not a transmission shop however, and they acknowledged this work would be as far as they can go.
My question is, does anyone know a shop in NC, SC or MD who is really good working on the MCT for a more all rounded transmission service?

Second shop confirmed that this issue is usually only seen at higher mileage. Their price out the door wet start-up clutch replacement including shift adaptation and one solenoid replacement (more if needed) is $2800. That sounds more reasonable for 5-8 hours of work and parts. MB clutch is $850, solenoid $130.
