    Is DTC P0806, P0807, or P0808 indicated?

    YES 

    The failure is duplicated. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM , then recheck. If this DTC goes away and the TCM was substituted, replace the original TCM .

    NO 

    Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the two-way clutch actuator valve stroke sensor and the TCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
