ISSUE
Some 2001-2003 Rangers, 2001-2003 Explorer Sport/Sport Trac, built prior to 10/18/2002, equipped with a 5R55E automatic transmission and 4.0L engine, may exhibit a gear whine type of noise in 1st and 2nd gear ONLY. This may be caused by the Reverse and Forward Planetary assemblies and/or the driveshaft.
ACTION
Verify that only these conditions exist and no DTCs are present. If other conditions are present and DTCs exist they must be diagnosed and serviced first. Once all other conditions are serviced and only the 1st and 2nd gear whine are still present, refer to the following Service Procedure. Using the chart provided, select the parts that need to be replaced.
NOTE
IF PLANETARIES ARE LISTED, BOTH MUST BE REPLACED.
SERVICE PROCEDURE
Gear Whine Service Procedure
1. Determine whether the driveshaft only, planetaries only or both driveshaft and planetaries need to be replaced, refer to Application and Component replacement chart shown.
2. If just the driveshaft needs to be replaced follow the procedures as listed in the appropriate Workshop Manual section for driveshaft removal/replacement.
3. If the planetaries need to be replaced, using the appropriate model and year Workshop Manual, Section 307-01, Transmission Removal procedures, remove the transmission.
