P0758: Shift Solenoid "B" Electrical
7 vehicles · 4 makes · $200-$5,000 repair
Most Reported On
P0758 is an OBD-II diagnostic trouble code meaning “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). 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. This code is most commonly reported on 2000-2002 Honda Passport, 2001-2003 Toyota RAV4 (2WD with 4-speed automatic, 4WD with 4-speed automatic), and 2000-2003 Lexus RX, plus 4 other vehicles, with repair costs ranging from $200 to $5,000.
