WARNING: This page is about a different car, the 2013 Honda Odyssey, 2012 Honda Odyssey, and 2011 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).

Warm up the engine to normal operating temperature (the radiator fan comes on).
Make sure that the transmission is filled to the proper level, and check for fluid leaks.
Drain the ATF (see ATF REPLACEMENT ) through a strainer. Inspect the strainer for metal debris or excessive clutch material.
Does the strainer have metal debris or excessive clutch material?

NO -Replace the ATF (see step 6 ), then go to step 4.
Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Test-drive the vehicle:
- P0796: Start the engine. With the brake pedal pressed, shift the transmission to 1st gear, then shift lever to R and drive the vehicle for at least 3 seconds. Slow down, and stop the wheels.
- P0797: Drive the vehicle with the shift lever in D for at least 11 seconds, and let the transmission shift through all five gears. Slow down, and stop the wheels.
Monitor the OBD status for P0796 or P0797 in the DTCs MENU with the HDS.

Clear the DTC with the HDS.
Select Clutch Pressure Control (Linear) Solenoid Valve C in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve C with the HDS.
Does the HDS indicate NORMAL?

YES -Intermittent failure, the system is OK at this time.

NO -Follow the instructions indicated on the HDS according to the test result. If the HDS has not determined the cause of the failure, go to step 10. If a part is replaced, go to step 11.
Inspect A/T clutch pressure control solenoid valve C (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE C TEST ).
Does A/T clutch pressure control solenoid valve C work properly?

YES -Replace the secondary valve body (shift valve C) or the transmission, then go to step 13.

NO -Replace A/T clutch pressure control solenoid valve C (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE C REPLACEMENT ), then go to step 13.
Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Test-drive the vehicle:
- P0796: Start the engine. With the brake pedal pressed, shift the transmission in 1st gear, then shift to R, and drive the vehicle for at least 3 seconds. Slow down, and stop the wheels.
