The Nissan Murano was first introduced in 2003. It is the largest Nissan to use the continuous variable transmission, or CVT. This transmission has no specific gear ratios. It has a multitude of varying ratios that are continuously changing in response to load and rpm to achieve the best fuel economy and power band. The 2003 Nissan Murano has a transmission dipstick on the right side of the transmission. There is no specified mileage or period for fluid replacement. A circuit that monitors the transmission will set a code if the transmission overheats, is subjected to unusual loads or internal problems. The dealer must clear these transmission codes to turn off the light.
Open the hood and locate the transmission dipstick on the right side of the transmission. Flip the fold over lock up and pull the dipstick out.
Examine the color of the fluid. It should be cherry red. Bar any internal problems, the fluid should stay this color for well over 100,000 miles. The transmission is a sealed unit, not exposed to the air. The only contamination comes from worn material resulted from the friction of the clutches.
Check the fluid level on the stick. The car must be on level ground for a good reading. The engine must be running, warm and the transmission in set in "park." The fluid level should be on the "full" line on the stick. If it isn't, a leak must be present.
Fill the transmission with CVT-NS2 fluid only. This transmission works at higher temperature levels and will not last with a different fluid. All transmission fluids differ in working temperature, pressure and additives to protect the seals. The wrong fluid can cause the transmission to overheat and experience rapid wear. If the transmission fluid turns brown, making it evident that there is a significant amount of clutch material in the fluid, it takes just over six quarts to re-fill.
