There is no single transmission fluid suitable for every vehicle. Conventional automatics, continuously variable transmissions, dual-clutch units, and manual transmissions may require very different lubricants.
The exact manufacturer specification matters. Fluid color, a familiar brand name, or a general description such as synthetic is not enough to confirm compatibility.
Certified Transmission at 1303 Fort Crook Rd. N. in Bellevue can identify the appropriate specification for your transmission. Avoid adding fluid or aftermarket additives unless their suitability and the correct checking procedure have been established.
