Thanks Mike Tangas,
so it is 2:0 for having them do the front seal and then me do the kickdown solenoid and the filler tube. Do you need to take of the pan and the exhaust to get more room or can it be done with the exhaust still there?
And what about that leak that started it all (see attached) Does anybody know what is behind there? (They said 2 o-rings but I cannot see anything on the MB Electronic Parts Cat.)
And then I still have to deal with the B2 piston, which is the scariest part. But that could may be dealt with at the next transmission service.
Thanks for all your help.
