P0758 on Lexus
Shift Solenoid "B" Electrical
P0758 on Lexus vehicles indicates shift solenoid "b" electrical. Au7o has documented this code across 1 Lexus model — most commonly on RX. This powertrain code indicates an electrical fault in the transmission's shift solenoid 'B' circuit. Shift solenoids are electrically controlled valves that route transmission fluid to engage the correct gears (solenoid B is commonly associated with the 2-3 shift). The transmission computer detected the solenoid circuit electrical value (voltage/current) outside the expected range. This can cause harsh or missed shifts, slipping, or the transmission entering limp mode, and should be addressed to avoid further transmission damage. Typical repair costs on Lexus range from $2,800 to $5,000, depending on the specific model and root cause.
Common Causes of P0758
- •Faulty shift solenoid B
- •Damaged, shorted, or open solenoid wiring/connector
- •Low or contaminated transmission fluid
- •Clogged or worn valve body passages
- •Internal transmission electrical (harness) fault
- •Faulty transmission control module (less common)
P0758 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 P0758 mean on Lexus?▼
P0758 stands for "Shift Solenoid "B" Electrical." This powertrain code indicates an electrical fault in the transmission's shift solenoid 'B' circuit. Shift solenoids are electrically controlled valves that route transmission fluid to engage the correct gears (solenoid B is commonly associated with the 2-3 shift).
