6 Speed Transmission Service - Best Order of Operations?

[alexpinson5]

Hi guys,

I have a 2000 Boxster S with ~40k miles on it, I'm working on dropping the transmission to a) verify and repair what I think is an RMS leak and b) replate a squealing throwout bearing. In addition I need to change the transmission gear oil.

I've been looking around but haven't found any answers either way - are there any advantages to draining the oil before dropping the transmission (weight is the one that immediately comes to mind) versus leaving it in, doing the service and reinstall, and then draining and refilling as I button things back up?
