How to Check Automatic Transmission
Fluid (4.6L Engine)
For the 4.6L V8 engine, it is not necessary to check the
transmission fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs, take the
vehicle to your dealer service department and have it
repaired as soon as possible.
