3. Run the engine at normal idle speed for at least 60
seconds, and leave the engine running for the rest of this
procedure.
4. Fully apply the parking brake, and press the brake
pedal.
5. Place the gear selector momentarily into each gear
position (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
6. Remove the dipstick, wipe it clean and reinsert it until
seated.
7. 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.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole. 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. Use ONLY
the specified fluid (see ⬙ Fluids And Lubricants ⬙ for fluid
specifications). 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 re-
checking the fluid level.
NOTE: 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 60-70°F / 16-21°C. Only use the COLD region
of the dipstick as a rough reference when setting the fluid
level after a transmission service or fluid change. Re-check
the fluid level, and adjust as required, once the transmis-
sion reaches 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 the
temperature is elevated enough to produce an accurate
reading. Run the engine at idle, in PARK, to warm the
fluid.
8. Reinsert the dipstick. Check for leaks. Release the park-
ing brake.
