Mazda CX-5 Service & Repair Manual: Control Valve Body Removal/Installation [Fw6 A EL, Fw6 Ax EL]

On-Vehicle Removal

WARNING:

• A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.

• Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eyeglasses whenever using compressed air.

CAUTION:

• If the control valve body has been replaced, perform initial learning..

• Placing the control valve body connector side pointed downward could damage the control valve body connector part or sensor. If the servicing can only be performed by pointing the control valve body connector side downward, spread shock-absorbing material, which does not produce dust or foreign matter, and place the control valve body connector part and sensor on the table so that they do not directly contact the table.

  

  
  

1. Select the selector lever to P position.

2. Disconnect the negative battery cable..

3. Remove the front under cover No.2..

4. Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.

5. Remove the air cleaner component..

6. Disconnect the control valve body connector.

CAUTION:

• Make sure that your hand does not touch the terminal as the connector terminal could be damaged.

• Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.

7. Remove the hose clamp.

8. Drain the ATF..

9. Remove the oil pan.

CAUTION:

• To avoid damaging the control valve body, if there is a large amount of foreign material at the bottom of the oil pan when the oil pan is removed, replace the oil strainer with a new one.

• If there is not a large amount of foreign material at the bottom of the oil pan, the oil strainer does not have to be replaced.

10. Remove the oil strainer.

11. Remove the oil strainer O-ring.

12. Remove the control valve body.

CAUTION:

• Remove the control valve body directly from underneath so that force is not applied to the control valve body connector in the lateral direction.

13. Remove the oil seal (control valve body)..

14. Remove the gasket from the transaxle case.

On-Vehicle Installation

1. Install the gasket to the transaxle case.

2. Install the dowel pin to the control valve body.

NOTE:

• If the dowel pin remains in the transaxle case, remove the dowel pin from the transaxle case and install the dowel pin to the control valve body.

3. Install the control valve body so that the parking assist lever component is engaged in the gap between the two surfaces of the spool part of the manual valve.

CAUTION:

• Install the control valve body so that the turbine/input shaft speed sensor, output shaft speed sensor, and control valve body connector do not contact the transaxle case.

  

  
  

Tightening torque

• 9—10 N·m {92—101 kgf·cm, 80—88 in·lbf}

4. Move the manual valve in both directions of the arrow and verify that the manual valve is correctly connected to the parking assist lever component and the slider pin for the range sensor.

NOTE:

• If the manual valve only moves in the gap between the parking assist lever component surface and the manual valve surface, the manual valve and the parking assist lever component are correctly engaged.

5. Install the oil strainer O-ring.

NOTE:

• If there is a large amount of foreign material at the bottom of the oil pan, replace the oil strainer with a new one.

6. Install the oil strainer.

Tightening torque

• 9—10 N·m {92—101 kgf·cm, 80—88 in·lbf}

7. Apply a light coat of silicon sealant (TB1217E) to the contact surfaces of the oil pan and transaxle case.

CAUTION:

• Clean any remaining silicone sealant on the contact surface of the transaxle case and oil pan, and degrease the sealant area. Otherwise, oil could leak.

8. Install the oil pan with new bolts before the applied sealant starts to harden.

Tightening torque

• 8—10 N·m {82—101 kgf·cm, 71—88 in·lbf}

9. Install the front under cover No.2..

10. Install the oil seal (control valve body)..

11. Install a new hose clamp to the position shown in the figure.

CAUTION:

• If the hose clamp is reused it could cause ATF leakage, therefore use a new hose clamp.

• Install the hose clamp tab to within the range shown in the figure.

  

  
  

  A: 210°

• Install the hose clamp so that it does not interfere with the top and bottom flanges of the oil seal to maintain the waterproofing integrity.

  

  
  

12. Connect the control valve body connector.

CAUTION:

• Make sure that your hand does not touch the terminal as the connector terminal could be damaged.

• Verify that there is no fluid or foreign matter adhering to the connector before connecting the connector.

• Insert the connector straight as the connector terminal could be damaged.

• Rotate the connector lever until a click is heard.

13. Add the ATF..

14. Install the air cleaner component..

15. Connect the negative battery cable..

16. Perform the “TCM configuration” (Control valve body Replacement)..

17. Perform the “Initial Learning” (Control valve body Replacement)..

18. Perform the “Mechanical System Test”..

19. Perform the “Road Test”..
