I have just started a 722.6 transmission rebuild out of a 2006 Sprinter. I have this posted over at sprinter-source.com but wanted to get the input of people on this forum also.

Alright well...I pulled it apart. Here are my pictures.

Here is the oil pump:

Here is the bell housing bearing surface (oil pump side). It is gouged.

B1 Clutch Outer Housing. There is some rough edges but relatively smooth:

K2, B3, and B2 Clutch Inner. Notice the significant gouging where the clutches contact on all three of these clutches:

B3 Clutch:

O-ring at K3 Clutch. This o-ring had broken down and there wasn't a lot left of it:

http://drive.google.com/uc?export=view&id=1T2EhY7mF-dvLIQkjuTVrPzeJwfYqmHq13Q

B2 Clutch Housing. Grooves/gouging present on the outer housing:

I'm concerned about the pitting at the bell housing at the oil pump. It looks like something must have gotten in the oil pump "chewed up."

I'm also concerned about all of the deformation on the surfaces that the clutches engage. How much is this is normal wear and what should be replaced?
