Thanks for the answers guys...my working on X5 recently got me post the question under the wrong car.
So here is my correction for Toyota Camry Hybrid 2007:
The front PSD fluid OE is toyota ATF WS. It seems the front PSD in Camry Hybrid is lubricated by the same fluid that is shared with
the front differential and there are NO other separate procedures for the replacement of the oil for the diff.
Once I do PSD fluid replacement I am done I assume. Reason I am asking, some Camry used to share fluid (not just type of fluid, actual fluid )
and refilling the transmission via fill whole was INSUFFICENT and you would run on dry diff if you did not fill the diff SEPARATELY.
BMW X5 2007 has it that way. There is FRONT DIFF, REAR DIFF, Transfer Box, TRANSMISSION all using individual fluids.
I am trying to get a hold of what it is for Camry HYBRID 2007.
I assume there is ONLY PSD fluid to be changed which is Toyota ATF WS and that is ALL for Camry Hybrid.
