| 1. | Warm up the engine to normal operating temperature (the radiator fan comes on). |
| 2. | Make sure that the transmission is filled to the proper level, and check for fluid leaks. |
| 3. | Drain the ATF through a strainer. Inspect the strainer for metal debris or excessive clutch material. Does the strainer have metal debris or excessive clutch material? YES - Replace the transmission.n NO - Replace the ATF, then go to 4. |

| 8. | Clear the DTC with the HDS. |
| 9. | Choose Clutch Pressure Control (Linear) Solenoid B in Miscellaneous Test Menu, and test the A/T clutch pressure control solenoid valve B with the HDS. Is the system OK? YES - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, retest the A/T clutch pressure control solenoid valve B with the HDS.n NO - Follow the instructions indicated on the HDS by the test result, but the tester has not determined the cause of the failure, go to 10. If any part is replaced, go to 11. |
| 10. | Inspect A/T clutch pressure control solenoid valve B. Does the A/T clutch pressure control solenoid valve B work properly? YES - Repair hydraulic system related with shift valve B, or replace the transmission, then go to 11. NO - Replace A/T clutch pressure control solenoid valve B,, then go to 11. |
| 11. | Clear the DTC with the HDS. |
| 12. | Test-drive the vehicle in the D position through all five gears at speeds over 20 km/h (12 mph) for more than 20 seconds, then slow down to a stop. |
| 13. | Retest-drive the vehicle in the D position through all five gears at speeds over 20 km/h (12 mph) for more than 20 seconds, then slow down to a stop. |
