Cold Check:
Note: The fluid level rises as its temperature rises. Do
not fill above the Cold Run band if the transmission fluid
is below normal operating temperatures.
1 The purpose of the cold check is to determine if the
transmission has enough fluid to be operated safely
until a hot check can be made.
2 Run the engine for at least one minute. Apply ser-
vice brake. Shift to Drive (D) and operate the engine
for 30 seconds at 1000 to 1500 rpm; then shift to
Reverse (R) to clear the hydraulic system of air.
Then shift to Neutral (N) and allow the engine to idle
(500 to 800 rpm).
3 With the engine running, remove the dipstick from
the tube and wipe clean.
4 Insert the dipstick into the tube and remove. Check
the fluid level reading. Repeat the check procedure
to verify reading.
5 If the fluid level is within the “COLD RUN” band, the
transmission may be operated until the fluid is hot
enough to perform a “HOT RUN” check. If the fluid
level is not within the “COLD RUN” band, add or
drain as necessary to bring it to the middle of the
“COLD RUN” band.
6 Perform a hot check at the first opportunity after the
normal operating temperature of 71–93
C (160–200
F) is reached.
