Cold Check
rv mm 26.02.000
Important: After replacing the transmission fluid or changing the filter(s), it is important to check the fluid level cold to determine if the transmission has a sufficient amount of fluid to be safely operated until a hot check can be performed.
- A cold check may be made when the sump temperature is 60 to 104°F (15 to 40°C).
- Run the engine for at least one minute to clear the fluid system of air.
- With the engine running, wipe the dipstick clean and check
the fluid level. Any level within the COLD RUN (lower) band is satisfactory
for operating the vehicle. See Fig.. If the level is
not within the COLD RUN band, add or drain fluid until it reaches
the middle of the COLD RUN band.
