INSPECTION
Lower and Upper Bodies

CAUTION: Be careful not to lose these parts.





NOTE:
^ Check to see that retainer plates are properly positioned in lower body.





^ Check to see that retainer plates are properly positioned in upper body.

Oil Strainer

NOTE: Check wire netting of oil strainer for damage.

Shift Solenoid Valves "A" and "B", Line Pressure Solenoid Valve, Torque Converter Clutch Solenoid Valve and Overrun Clutch Solenoid Valve





^ Measure resistance.
^ For shift solenoid valve A, refer to "Diagnostic Procedure".
