Jeep Wrangler: Automatic Transmission — If Equipped / Special Additives
FCA strongly recommends against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered
product and its performance may be impaired
by supplemental additives. Therefore, do not
add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick...
