There is no need to check the transmission fluid level.

A transmission fluid leak is the only cause of fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible.

Change the fluid at the intervals specified in the Maintenance Schedule, and be sure to use the transmission fluid specified in Recommended Fluids and Lubricants.

There is a special procedure for checking and changing transmission fluid. Because this procedure is complex, it must be performed by your dealer.
