Jeep 2008 Liberty - Manual (Page 425)

Automatic Transmission
Fluid Level Check
Your vehicle is equipped with a capped dipstick tube that
is sealed and it should not be tampered with. Your
authorized dealer has the proper tools to ensure that the
fluid level is set properly.
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 that
recommended by the manufacturer will result in
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in this sec-
tion for the correct fluid type.
Fluid and Filter Changes
Change the automatic transmission fluid and filter at the
intervals shown in the “Maintenance Schedule” in Sec-
tion 8 of this manual.
In addition, change the fluid and filter if the transmission
is disassembled for any reason.
NOTE: Be sure to follow the “police, taxi, fleet, off-road,
or frequent trailer towing” maintenance interval if appli-
cable.
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.
