Primary Control Valve Body 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.

1. Remove the battery cover..

2. Disconnect the negative battery cable.

3. Remove the aerodynamic under cover NO.2..

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

5. Drain the ATF..

6. Remove the oil pan.

7. Remove the oil strainer.

8. Disconnect each solenoid valve connector and GND.

9. Remove the bolts as shown, then remove the primary control valve body.

10. Remove the accumulators and accumulator springs.

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

6. Drain the ATF..

7. Remove the oil cover.

8. Disconnect each solenoid valve connector.

9. Remove the bolts and GND as shown, then remove the secondary control valve body.

10. Remove the tubular pin and O-ring.

Secondary Control Valve Body On-Vehicle Installation

1. Install the tubular pin and new O-rings to the transaxle case.

2. Install the secondary control valve body.

3. Tighten the bolts and GND as shown to install the secondary control valve body.

Tightening torque

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

Bolt length measured from below the head


Mark	Length measured from below the head
B	40mm {1.575 in}
C	50mm {1.967 in}
