Upper to Lower Control Valve Body Assembly Assemble

Callout

Component Name

1

Control Valve Body Ball Check Valve (Qty: 7)

Notice: Do not use any type of grease or other material to hold the check ball valves in place during assembly. Grease will cause the valves to not operate properly, resulting in damage to the transmission.

Tip
Refer to Ball Check Valve Locations .

2

Control Valve Body Spacer (w/Gasket) Plate Assembly

Notice: Do not use the old spacer plate. Install a NEW spacer plate. Reusing an old spacer plate may cause internal transmission leaks and transmission damage.

3

Control Valve Lower Body Assembly

Tip
Turn the valve body assembly over after installing to upper body.

4

Bolt M5 x 36 (Qty: 12)

Notice: Refer to Fastener Notice in the Preface section.

Procedure

Tighten the bolts in the sequence shown.

Component Name

1

Filter Plate Assembly

Notice: Use care when handling the control valve body assembly. If dropped, damage to the control solenoid valve body assembly internal components, including the transmission control module (TCM), may result.

Notice: Discard the filter plate. Replace with a NEW filter plate. Reusing an old filter plate may cause damage to the control solenoid valve assembly.

Tip
Use care when removing or installing the filter plate assembly. However, if a retaining tab is broken or missing, do not replace the control solenoid valve assembly. The filter plate assembly can still be adequately aligned.
