P0773 on Lexus
Shift Solenoid "E" Electrical
P0773 on Lexus vehicles indicates shift solenoid "e" electrical. Au7o has documented this code across 1 Lexus model — most commonly on RX. 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. Typical repair costs on Lexus range from $2,800 to $5,000, depending on the specific model and root cause.
Common Causes of P0773
- •Failed shift solenoid E (open or shorted coil)
- •Damaged or corroded wiring or connector
- •Short to power or ground in the solenoid circuit
- •Low or contaminated transmission fluid affecting the solenoid
- •Internal transmission harness fault
- •Faulty transmission control module (less common)
P0773 on Lexus by Model
Lexus RX(1 issue)
- U140E/U151E Automatic Transmission Failure from Burned Planetary Gearset and Delayed Engagement2000-2003
Early first-generation RX300 models are well known for premature automatic transmission failure, especially on AWD vehicles but also on FWD examples. Owners report delayed engagement into Drive or Reverse, harsh shifting, slipping on acceleration, and eventual loss of movement; teardown reports commonly cite burned clutches and damaged planetary gear components. The issue is widely documented in owner communities, repair databases, and NHTSA complaints, and is often attributed to a transmission that runs hot and is heavily stressed by vehicle weight.

What does P0773 mean on Lexus?▼
P0773 stands for "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. On Lexus specifically, this code is documented across 1 model.
