Do not use supplemental transmission fluid additives because they are unnecessary and could lead to transmission damage that may not be covered by the vehicle Warranty.
The transmission does not consume fluid. However, if the transmission slips or shifts slowly you should check the fluid level. If you notice a sign of leaking fluid, contact an authorized dealer.
Checking the Transmission Fluid Level*
Only check the transmission fluid level when the engine is at normal operating temprature 179–199°F (82–93°C). Normal operating temprature is reached after driving approximately 20 mi (30 km).

Low Fluid Level
If the fluid level is within the minimum range (below point A) add the correct specification fluid to be within the hash mark area.   See   Capacities and Specifications
Note:   If the fluid level is below the minimum range do not drive your vehicle. An underfill conition can damage the transmission.
Correct Fluid Level
If the fluid level is within the hash mark area (between points A and B) do not add any fluid.
High Fluid Level
If the fluid level is above the maximum range (above point B) fluid may need to be removed. High fluid levels may be caused by a overheating condition. If you have operated your vehicle at high speeds, towing a trailer or in city traffic during hot weather, allow your vehicle to cool for a minimum of 30 minutes before rechecking the level.
Note:   An overfill condition can damage the transmission.
