Speed Sensor replacement

[R33_Guy]

Hey all. I’m looking on replacing my speed sensor on my R33 GTR. Will the center differential need to be drained, and if so, the center diff uses ATF fluid D? I found information on the transmission, front diff and rear diff. Can’t find a for sure answer for the center diff. Any help will be greatly appreciated.

Yes it is ATF. I quote @Duncan "it takes a good synthentic auto trans fluid like Castrol Transmax Z"

It's not a diff. It's a transfer case. Totally different thing.

Yes, fluid will come out the sender hole. No you do not really need to drain it. Just pull the old, quickly poke the new, clean up and top up. But realistically, you should probably take the opportunity to change it anyway.

Thank you so much for the help

Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
