Jeep Wrangler: Automatic Transmission — If Equipped / Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not
required. However, change the fluid and filter if
the fluid becomes contaminated (with water,
etc.), or if the transmission is disassembled for
any reason.
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...
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer specified transmission fluid...

If you store quantities of fuel, good
maintenance of the stored fuel is also essential.
Fuel contaminated with water will promote the
growth of “microbes.” These microbes form
“slime” that will clog the fuel filtration system
and lines. Drain condensation from the supply
tank and change the line filter on a regular
basis...
