High Fluid Level
High fluid levels can be caused by an overheating condition.
Adjusting Automatic Transmission Fluid Levels
Note: Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick handle and also in the
Capacities and Specifications chapter.
If necessary, add fluid in
tube until the level is correct.
Note: An overfill condition of transmission fluid may cause shift or
engagement concerns or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
Manual Transmissions
Note: Use of a non-approved transmission fluid may cause internal
transmission component damage.
See the Scheduled Maintenance chapter for scheduled intervals for
fluid checks and changes.
Your manual transmission may be filled with an optional synthetic fluid
which allows the use of extended service intervals. A tag on the filler
plug identifies the use of the synthetic fluid.
Only use fluid that meets manufacturer specifications. See Technical
specifications in the Capacities and Specifications chapter.
