ISSUE
Some 2009 Escape and Mariner vehicles equipped with a 6F35 automatic transmission and built before 8/29/2008 may exhibit a continuous knocking noise heard with the engine running and vehicle stationary or moving slow. The noise is heard in drive and/or reverse, and is not typically heard in neutral and/or park. This noise may be due to the torque converter assembly.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
NOTE
IF THE VEHICLE HAS A 3.0L V6, AUTOMATIC TRANSMISSION, AND THE NOISE IS HEARD IN ALL 4 POSITIONS (P,R,N,D), THEN THIS PROCEDURE DOES NOT APPLY.
1. Verify vehicle was built before 8/29/2008 and the noise is continuous knocking noise, heard from rear of engine and/or front of transmission, with engine running and vehicle stationary or moving slow.
a. Is the noise present in (D) and/or (R) but not in (N) and/or (P)? If yes, then go to Step 2.
b. Is the noise is heard in all four positions (P,R,N,D)? If yes, then stop. This procedure does not apply and refer to Workshop Manual (WSM), Section 303-00.
2. Use chassis ears to listen for noise at the bottom of the transmission near the torque converter access hole. If noise is present, then replace the torque converter per WSM, Section 307-O1A
