Automatic Transmission
Selection Of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only the manufacturer’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. It is important that the transmission fluid be main-
tained at the prescribed level using the recommended
fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will require
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
498 MAINTAINING YOUR VEHICLE

CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
Regular automatic transmission fluid level checks are not
required. For this reason the dipstick is omitted.
If you notice fluid loss or transmission slippage or
malfunction, have your authorized dealer check the
transmission fluid level.
CAUTION!
The fluid level is preset at the factory and does not
require adjustment under normal operating condi-
tions. If a transmission fluid leak occurs, visit your
authorized dealer immediately. Severe damage to the
transmission may occur. Your authorized dealer has
the proper tools to accurately adjust the fluid level.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle.
