Well like it says he in the title, my ES won't shift electronically. I can shift with the emergency shifter but not by buttons. In the beginning, it would shift up to 5th, but not back. After using the hand shifter, it won't shift either way with the buttons. Any ideas would be appreciated.
First, check fuses. Sounds stupid, but a lot of problems can be solved this way. If it's not that, check to see if the buttons are allowing the electric signal. Use a test lamp and probe the wires while pushing the buttons. If electricity is flowing, check the shifting solenoid. That's a bare bones check list that I'd start with.
