This is the transmission oil found in the GTR's transmission from the factory.
R35 transmission oil is a specialist product, not an off the shelf D-Matic or Transmax ATF. A conventional ATF will in fact cause problems with the dual wet clutches. This is the 'key' to R35 transmission oil, keeping the clutches happy and healthy with a nice slick action, which is why Nissan have sacrificed lubricity and metal protection in the quest for the very best shift action and 'driver comfortable' clutch engagement.
Sold as 1 quart, the GTR holds 9 and 7/8 quarts.
