Jeep 2013 Wrangler - Manual (Page 589)

4. Place the shift lever momentarily into each gear posi-
tion (allowing time for the transmission to fully en-
gage in each position), ending with the shift lever in
PARK.
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
The fluid level should be between the HOT (upper)
reference holes on the dipstick at normal operating
temperature. If the fluid level is low, add fluid through
the dipstick tube to bring it to the proper level. Do not
overfill.
After adding any quantity of oil through the
dipstick tube, wait a minimum of two minutes for the
oil to fully drain into the transmission before recheck-
ing the fluid level.
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 be-
tween 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). Remember it is best
to check the level at the normal operating temperature.
CAUTION!
Be aware that if the fluid temperature is below 50° F
(10° C), it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.
