Seems that error traces to:
"Upshift Delay Switchover Valve" or "Transmission Indeterminate Failure"

Possible causes being:
Faulty Transmission Shift Control Valve
Transmission Shift Control Valve harness is open or shorted
Transmission Shift Control Valve circuit poor electrical connection

I occasionally get odd transmission errors like that. My troubleshooting steps would be checking the battery connections to make sure they're tight, make sure the battery itself is healthy, disconnecting the battery for 30 min, and eventually clearing the code using my UltraGauge. If it comes back then there's definitely a real problem. If not, I usually just chalk it up to the car being weird.
