1996 Lexus ES 300 • 6 cylinder Automatic • 147,800 miles

Check engine code on 1996 Lexus ES300 shows PO770. Dealer says could be one or two different solenoid sensors. The part #s are: 8542033010 & 3527033011. Do I need to replace both or how do I know which one to replace?

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.
