The 64U20 or 64U75. The U75 was a replacement available through a TSB for customers complaining of shift shock when the torque convertor locks and unlocks...

Helps that I have one sitting beside me at my desk... :D Those TSBs at http://www.infiniti-techinfo.com are an invaluable resource! I'd say second to anything posted by Q45Tech, they're the best source for information on fixing problems that aren't in the the service manual, and for fixing those annoying little problems that crop up in every model year.
