Six quarts of genuine Nissan Matic S ATF, part 999MP-MAT00S, plus a new drain plug crush washer for a drain-and-fill on Nissan and Infiniti automatics.
This is a drain-and-fill kit for Nissan and Infiniti conventional automatic transmissions that call for Matic S fluid. It contains six quarts of genuine Nissan Matic S ATF, part number 999MP-MAT00S, and a new crush washer for the drain plug.
Matic S is the factory fill for the 5-speed RE5R05A used in trucks and SUVs such as the Titan, Armada, Frontier, Xterra and Pathfinder, along with several Infiniti rear-drive models. Using a multi-vehicle ATF in these units can change clutch friction behavior, which shows up as harsh or flared shifts and shudder. Running the specified fluid avoids that.
A single drain and fill replaces only part of the fluid in the unit, since the rest stays in the converter and cooler lines, so six quarts is a practical amount for one service or for topping off after a pan drop. Always replace the drain plug washer when the plug comes out; a reused washer is a common source of a slow drip. Check your owner's manual or service information to confirm your transmission calls for Matic S and to get the correct check procedure and fill level.
Not for CVT transmissions. Nissan CVTs use NS-2 or NS-3 fluid, not Matic S.
