Assuming transmission is already removed, and so is the clutch/pressure plate and flywheel, how much time in labor should it take to replace the rear main seal?

Are any parts needed aside from the rear main seal itself?

If trans a nd flywhel are removed, I'd say no more than an additional hour. Its literaly behind the flywheel. A rear main seal puller makes things much easier. BMW has a special tool. Not sure if anyone has used a generic seal puller.

Yep, an additional hour at maximum is needed. I just did mine the other day, and what I did was order a new rear main cover that has the seal already installed, and comes with a new gasket for the back of the cover as well as all new bolts and bolt gaskets/washers. My cost was around $80 for this, but for me it was worth it not having to pry out the old seal and carefully press in a new one-just swap the covers and you are done. The part number needed is 11 14 1 436 109.
