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.

The Boxster & Cayman have a transaxle, which contains both transmission & differential in the same case, with shared fill & drain plugs, and they take the same fluid.

This is supposed to be the factory transaxle fluid, you'll need three quarts:

Put one tube of this in there for some extra moly molybdenum: Pelican Parts - Product Information: 2019-M19

Here's an article on how to do it all:

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.
