ISSUE

Some vehicles equipped with the 4R70W automatic transmission may exhibit a
"Ticking" or "clicking" type noise in first gear. This may be caused by the intermediate clutch moving inside the transmission.

ACTION

Install an intermediate clutch anti-rattle clip to correct noise. Refer to the following Service Procedure for details.

SERVICE PROCEDURE

1. Verify clicking noise in first (1st) gear only.

2. Lift and support vehicle. Refer to the appropriate model year Workshop Manual, Section 100-02.

3 Remove the transmission from the vehicle. Refer to Workshop Manual, Section 307-01.

4. Remove the torque converter and the front pump assembly from the transmission. Remove and discard front pump gasket. Refer to Workshop Manual, Section 307-01.

5. Before installing the anti-rattle clip, push on the clutch plates opposite the 1 o'clock case position. This will provide the maximum opening for the clip to be installed and assure that the rattle clip seats properly on the pressure plate face.

NOTE:
USE CAUTION WHEN REMOVING PUMP ASSEMBLY FROM TRANSMISSION. THE REVERSE CLUTCH AND FORWARD CLUTCH CYLINDER ASSEMBLIES CAN BE MOVED SO THAT THE DRIVING HUBS DO NOT ENGAGE ALL THE FRICTION PLATE DRIVE SPLINES. THIS WILL CAUSE THE TRANSMISSION END CLEARANCE TO BE REDUCED AND DAMAGE CAN RESULT.








6. Install new Intermediate Clutch Anti-Rattle Clip (YL3Z-7A609-AA) in the center of the 1 o'clock case position. Push clip in until fully seated. (Figures 1 and 2).

7. Check that the intermediate clutch and transmission end clearances are correct. Refer to Workshop Manual, Section 307-01.

8. Install transmission pump assembly using a new Pump Gasket (F2VY-7A1 36-A). Refer to Workshop Manual, Section 307-01.

9. Install the transmission and lower vehicle.

10. Fill transmission to the correct level.
