258 Vehicle Care
Automatic Transmission
Fluid
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 the
dealer and have it repaired as soon
as possible.
Change the fluid at the intervals
listed in Maintenance Schedule
0 339, and be sure to use the
transmission fluid listed in
Recommended Fluids and
Lubricants 0 348.
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the correct
automatic transmission fluid. See
Recommended Fluids and
Lubricants 0 348.
The transmission fluid will not reach
the end of the dipstick unless the
transmission is at operating
temperature. If you need to check
the transmission fluid level, take the
vehicle to your dealer.
