No

Repair the connections as necessary.

=>Go to Repair verification.

6. Sensor inspection

1) Inspect the turbine speed sensor and output speed sensor for the following. Is the result normal?

  • Damaged sensor
  • Loose or improperly installed sensor
  • Excessive clearance
  • Foreign material passing between the turbine speed sensor and the direct clutch assembly and forward clutch assembly
  • Foreign material passing between the output speed sensor and the parking lock gear
  • Damaged direct clutch assembly and forward clutch assembly and parking lock gear

Yes

=>Go to Line pressure test.

No

Repair as necessary.

=>Go to Repair verification.

7. Line pressure test

1) Perform the line pressure test. Is the line pressure within the specified range?

Refer to "206.Transmission, Transaxle 19C.Functional Inspection(AWR6B45) measurement of the automatic transmission operating pressure".

Yes

=>Go to Solenoid inspection.

No

Repair as necessary.

=>Go to Repair verification.

8. Solenoid inspection

1) Inspect the following solenoids in the valve body assembly. Are all of the results normal?

  • Shift solenoid (SL)
  • Clutch control solenoid (SL4)

Refer to "5.Transmission, Transaxle 5B.Automatic(AWR6B45) transmission inspection".

Yes
