You have to go thru the trouble tree to find the problem I posted the code description and the trouble tree to follow. Let me know what you find.
DTC P0770 Shift Solenoid E Malfunction (Shift Solenoid Valve SL)
The ECM uses the signals from the Throttle position sensor, Air-flow meter and crankshaft position sensor to monitor the engagement condition of the lock-up clutch.
Then the ECM compares the engagement condition of the lock-up clutch with the lock-up schedule in the ECM memory to detect mechanical trouble of the shift solenoid valve SL, valve body and torque converter clutch.
