2015 JEEP WRANGLER ECU

NOTE:
•The holes in the dipstick will be full of fluid if the
actual level is at or above the hole.
•If it is necessary to check the transmission below the
operating temperature, the fluid level should be
between the two COLD (lower) holes on the dipstick
with the fluid at approximately 80° F (27° C). If the
fluid level is correctly established at 80° F (27° C), it
should be between the HOT (upper) reference holes
when the transmission reaches 180° F (82° C). Re-
member it is best to check the level at the normal
operating temperature.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may
not register on the dipstick. Do not add fluid until
(Continued)
CAUTION!(Continued)
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid.
8. Reinstall the engine cover and snap it down securely
onto the four mounting studs.
9. Check for leaks. Release the parking brake.
NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated position, as long as its seal remains
engaged in the dipstick tube.
