Sourcing you own fluid for use by the shop should not be a problem. Just make sure the shop doesn't try to charge you for conventional fluid they didn't dispense, and make sure they return whatever supplied fluid that wasn't used. If they balk, find another shop. What could be a problem, though, is whether a Dexron III fluid such as Mobil 1 Synthetic ATF is compatible with the frictional requirements of the bands and clutch packs in your Nissan transaxle if it's an automatic unit. Good luck.
