ISSUE
Some vehicles, built prior to 8/01/2001, may exhibit a "whine" or "howl" noise during cold starts at temperatures below 4° C (40°F). This noise may be caused by the transmission fluid filter.

ACTION
Verify that the noise ONLY occurs during start up with ambient temperatures below 4°C (40 °F). If the noise is present only under those conditions replace the transmission fluid filter. Refer to the following Service Procedures for details.

SERVICE PROCEDURE

1. Raise vehicle on a hoist.

2. Drain the fluid from the pan.

3. Remove the pan and gasket.





4. Replace the original filter with the new service filter 1L2Z-7A098-AC (Figure 1).

5. Clean the pan.

6. Reinstall the fluid pan gasket and pan. Tighten the screws in a crisscross pattern to 11 N.m (8 lb-ft).

7. Add fluid and adjust to the proper level, refer to the workshop manual procedure, Fluid Level Check.

8. If the noise is still present after the fluid filter has been replaced, follow normal diagnosis for noise concerns using the Diagnosis by Symptom Charts in the Workshop Manual (Section 307-01).
