I went to the Toyota dealer . Since there is no clear diagram of where the solonoid is located I asked the Toyota dealer if I could buy and replace the solenoid. His answer was it was a difficult task. The whole transmission has to be dropped and solenoid replaced. Is this true ? Can I unscrew the pan and do it myself? Your help will be very much appretiated.

I had a same problem the code PO 0770 Shift solenoid E malfunction. I dropped the oil pan and tested the number 2 solenoid with compress air, the solenoid was leaked. I replace the solenoid and cleared the Engine Light. the car ran good for couple of days, then the Engine check light came back. I check the OBD II code. this time it shown me code PO0770 SHIFT SOLENOID E only. It did not show the "Malfuntion". I think the tranny has over 200K miles, it may be heavy contamination and blocked off the oil path and caused dropping pressure, the EGR may get a false reading and displays the Solenoid E malfunction.
