1. Install the accumulator springs, accumulators and control valve body.

Accumulator spring specification

2. Tighten the bolts as shown to install the control valve body.

Tightening torque

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

Bolt length measured from below the head

3. Install the oil strainer.

4. Match the harness colors, then connect each solenoid valves connector. Connector color (harness-side)

5. Install the GND.

Tightening torque

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

CAUTION:

• The removed bolts with spring washer cannot be reused. If they are reused, it could loosen the bolts due to spring weakness.

Tightening torque

• Flange bolt: 6.0-8.0 N*m {62-81 kgf*cm, 54-70 in*lbf}
• Bolt with spring washer: 8-10 N*m {82-101 kgf*cm, 71-88 in*lbf}

9. Add the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT).
