I have just purchased a 2008 ZD30 CRD patrol wagon with the 4spd auto. I want to give it a thorough service first up including changing the auto transmission oil/filter.

I read something in a manual about not mixing the auto gearbox oil & transfer case oil. I'm presuming this means to use the same oil in both boxes.

I was thinking of getting a few bottles of Gulf Western Syn-TS trans fluid. Would that be suitable in the transfer case?
