SERVICING AND MAINTENANCE 441
5. Place the gear selector momentarily into each gear posi-
tion (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 spec -
ified fluid (see "Fluids And Lubricants" for fluid specifica -
tions). 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 rechecking the
fluid level.
NOTE:
If it is necessary to check the transmission below the oper -
ating temperature, the fluid level should be between 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 trans
-
mission service or fluid change. Re-check the fluid level, and
adjust as required, once the transmission reaches normal
operating temperature.
8. Reinsert the dipstick. Check for leaks. Release the parking brake.
NOTE:
If it is necessary to check the transmission below the oper -
ating temperature, the fluid level should be between the two
COLD (lower) holes on the dipstick with the fluid at 68-86°F
/ 20-30°C. Only use the COLD region of the dipstick as a
rough reference when setting the fluid level after a transmis -
sion service or fluid change. Re-check the fluid level, and
adjust as required, once the transmission 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.
