DiaQueen SSTF-1 Transmission Fluid, 4-Liter

The Mitsubishi DiaQueen SSTF-1 is a genuine OEM transmission fluid, supplied in a 4-liter container, formulated specifically for the demanding requirements of the Mitsubishi Lancer Evolution X MR equipped with the Sportronic Shift Transmission (SST). Using the correct, manufacturer-recommended fluid is vital for maintaining the longevity and performance of this advanced transmission system. This particular fluid is officially designated as SSTF-1 and carries the Mitsubishi part number C0002610. It is critical to use this specific DiaQueen fluid, as indicated by multiple sources and the manufacturer's recommendations, to avoid voiding the transmission's warranty and to ensure optimal operation. The Evo X MR's SST transmission typically requires 8 liters of fluid for a complete change, meaning two 4-liter cans are necessary for a full service. Mitsubishi suggests a first fluid change at 5,000 miles, with subsequent changes recommended every 5,000 to 7,500 miles, depending on driving conditions. In addition to the fluid, replacing the OEM transmission filter (part number 2513A040) is also a recommended part of the service. Proper fluid level checking involves running the engine, cycling through gears, and checking the level while the vehicle is idling and fully warmed, as there is no traditional dipstick; specific bolts may be used to gauge the correct fill level on some setups. This fluid is explicitly stated to be for the 2008-2015 Mitsubishi Evolution X MR Auto SST. It ships by ground to the Lower 48 Continental United States ONLY and is not available for expedited shipping or for delivery to Alaska, Hawaii, or Puerto Rico.
