Hot Check:
Note: The fluid must be hot to insure an accurate check.
The fluid level rises as the temperature increases.
1 Operate the transmission in Drive (D) range until
normal operating temperature is reached:
•
sump temperature 71–93 C (160–200 F)
•
converter-out temperature 82–104 C (180–220
F)
2 Park the vehicle on a level surface and shift to Neu-
tral (N). Apply the parking brake and chock the
wheels. Allow the engine to idle (500–800 rpm).
3 With the engine running, remove the dipstick from
the tube and wipe clean. Insert the dipstick into the
tube and remove.
4 Check the fluid level reading. Repeat the check pro-
cedure to verify the reading.
5 If the fluid level is not within the “HOT RUN” band,
add or drain as necessary to bring the fluid level to
within the “HOT RUN” band.
