5. Inspect the color of the uid on the dipstick.
6. If the uid level is below the COLD check line, add only enough uid as necessary to bring the level
into the COLD line. It does not take much uid, generally less than one pint (0.5L). Do not overll.
7. If the uid level is in the acceptable range, push the dipstick back in all the way, then ip the handle down to
lock the dipstick in place.
8. Perform a hot check at the rst opportunity after the transmission reaches a normal operating temperature
between 82–93°C (180–200°F).
Hot Check Procedure
Use this procedure to check the transmission uid level when the TFT is between 82–93°C (180–200°F). The hot check
procedure is the most accurate method to check the uid level. The hot check should be performed at the rst opportunity
in order to verify the cold check. The uid level rises as uid temperature increases, so it is important to ensure the
transmission temperature is within range.
1. Start the engine and locate the transmission dipstick at the rear of the engine compartment, on the
passenger side of the vehicle.
2. Flip the handle up, and then pull out the dipstick and wipe the dipstick end with a clean rag or paper towel.
3. Install the dipstick by pushing it back in the dipstick tube all the way, wait three seconds and then pull it
back out.
NOTE: Always check the uid level at least twice. Consistent readings are important to maintaining proper uid level. If
inconsistent readings are noted, inspect the transmission vent assembly to ensure it is clean and unclogged.
4. Keep the dipstick tip pointing down and check both sides of the dipstick. Read the lower level. Repeat the
check procedure to verify the reading. Reference Figure 2.3.7-2.
