Durango 2WD V6-3.7L (2009)
Fluid - A/T: Description and Operation
AUTOMATIC TRANSMISSION FLUID
NOTE: Refer to Service Procedures for fluid level checking procedures.
Dexron VI Automatic Transmission Fluid is the only recommended fluid for the Hybrid transmission.
Mopar(R) ATF +4, Automatic Transmission Fluid is the recommended fluid for most Chrysler automatic transmissions.
Dexron II fluid IS NOT recommended. Clutch chatter can result from the use of improper fluid.
Mopar(R) ATF +4 as well as Dexron VI Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified from other
fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is
driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF has a unique odor that may change with age.
Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.
FLUID ADDITIVES
Chrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks.
Various "special" additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve
converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been supported to the satisfaction of Chrysler
and these additives must not be used. The use of transmission "sealers" should also be avoided, since they may adversely affect the integrity of
transmission seals.
