Just a couple of questions on removing the driveshaft from my 89 535 this weekend.I'm replacing the center support bearing.

Do I need to remove the transmission support to get access to the 4 nuts that bolt the driveshaft to the transmission, then support it with a jack and piece of wood? It looks like you can't get a wrench in there without removing it.

Will the transmission leak out the back, once I remove the driveshaft.
