Does the Cayman S transmission and rear differential take the same 75W-90 gear lube?

I saw the excellent article on the LSD install and how to change it out, including fluid draining and fill locations. But I am unsure if the trans and rear diff both get drained and filled in the same location or if they are different.

Thanks so much!!

I was pretty sure that they were like my father-in-law's STi. It too shares the transmission and diff. in the same case. Both also take gear lube. My old EVO 8 on the other hand, had separate transmission fill and drain and the transfer case and front diff shared a common fill and drain plug. With the EVO, the transmission took manual transmission fluid and the diff and transfer case took gear oil.
