P0773 is an OBD-II diagnostic trouble code meaning “Shift Solenoid "E" Electrical.” This code indicates the transmission control module detected an electrical problem in the circuit for shift solenoid E, such as an out-of-range current or voltage. Shift solenoids electronically route transmission fluid to engage gears, so an electrical fault can disrupt shifting. The vehicle may shift harshly, get stuck in a gear, or enter a limp/failsafe mode. The issue is electrical (wiring or the solenoid coil) rather than purely mechanical. This code is most commonly reported on 2000-2003 Lexus RX, with repair costs ranging from $2,800 to $5,000.
