Diagnostic Procedure

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure transaxle is at operating temperature. Check and adjust fluid level. See appropriate SERVICING article in AUTOMATIC TRANSMISSIONS. Place vehicle on hoist. Run vehicle under conditions to duplicate noise. Ensure noise originates from transaxle. If noise originates from transaxle, go to next step. If noise does not originate from transaxle, repair component causing noise.
    2. NOTE: Ensure radio is off. Alternator noise can transfer through speakers and be misinterpreted as transaxle oil pump wine.
  2. With gearshift lever in "N" position, increase engine speed. If noise pitch changes with increase of engine speed, go to next step. If noise pitch does not change with increase of engine speed, go to step  4.
  3. Transaxle has an internal problem. Inspect bearings in front half of transaxle. If bearings are okay, replace oil pump. See appropriate OVERHAUL article.
  4. Transaxle has an internal problem. Inspect bearings, pinion gears, etc. Repair as necessary. See appropriate OVERHAUL article.
