Patriot 4WD L4-2.4L (2009)
Fluid - CVT: Description and Operation
TRANSMISSION PTU AND RDA FLUIDS
NOTE: Refer to the maintenance schedules for the recommended maintenance (fluid/filter change) intervals for this transaxle.
NOTE: All transaxles have a common transmission and differential sump. Filling the transaxle accommodates the differential as well.
TRANSMISSION - PTU AND RDA FLUIDS
Mopar (R) CVT+4 is required in the CVT automatic transaxles.
Mopar (R) CVT+4 when new is green in color. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown.
This is normal. A dark brown/black fluid accompanied with a burnt odor and/or deterioration in shift quality may indicate fluid deterioration or
transmission component failure.
BG6 and T355 Manual transaxles require the use of Mopar (R) ATF+4 (Automatic Transmission Fluid).
PTU and RDA use Mopar (R) Gear AND Axle Lubricant SAE 80W-90 API GL 5 or equivalent non-synthetic product.
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.
