I have 1996 E320 with a M104 and 722.329 transmission and have been chasing a leak, I put some UV dye in the transmission and found I lave a decent leak from both the front and rear servo's on the passenger side of the transmission. How difficult is this to repair, not much data I can find, it appears that both servo covers are held in by a C-clip that is released by pushing in the servo cover and removing the C-clip and servo cover.

There is then a rubber gasket there that appears to be my problem, has anyone done this job before or have any tips.
