How to diagnose and fix P0758: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Honda Civic · 1996–1999
The 4-speed automatics on 1990s D16 Civics develop slipping and harsh or stuck shifting. Frequent causes are a failing shift-control solenoid and, distinctively, the distributor O-ring leaking oil onto the transmission solenoid connectors. Torque-converter breakdown that burns the fluid is the more severe failure mode and worsened into the following (2001+) generation.
Common Symptoms
- Transmission slips or engine revs without moving
- Harsh or delayed shifts, stuck in gear
- Burnt-smelling ATF
- Oil on the transmission solenoid connectors
- Shudder under light acceleration
How to Fix
Diagnose first: replace/clean shift-control solenoids and repair the leaking distributor O-ring so oil stops fouling the connectors; service fluid with genuine Honda ATF. Burnt fluid or converter failure requires transmission rebuild or replacement (a good used/JDM D16 automatic is a common budget path).

Honda Accord · 1995–1999
The Honda 4-speed automatic in the mid-to-late 1990s Accord is prone to slipping and outright failure, typically around/after 100,000 miles. As the internal clutch material wears, debris circulates in the fluid and clogs the shift solenoids, causing harsh or delayed shifts, flaring, and eventual loss of drive. The V6 automatic (2.7L C27A4 in 1995-1997, 3.0L J30A1 from 1998) is especially notorious, and the failure mode carried into the 1998-2002 V6 cars, which became one of Honda's most infamous transmissions of the era. Owners who never serviced the fluid (Honda ATF, every ~30k) fare worst.
Common Symptoms
- Slipping / RPM flare between gears
- Harsh or delayed shifts, thud on engagement
- No drive in a particular gear (e.g. no 4th)
- Loss of power / acceleration
- Burnt-smelling or dark transmission fluid
How to Fix
Early on, a fluid-and-filter service with genuine Honda ATF and solenoid inspection/cleaning can slow the decline. Once slipping is established, the accepted repair is a full rebuild (new clutch packs, solenoids, torque converter, and cooler flush) or a remanufactured/used transmission. Always flush the cooler and lines to prevent re-contaminating a fresh unit.

Toyota Corolla · 2005–2008
2005-2008 Corolla models with the 1ZZ-FE engine and two-wheel drive are documented for engine control module failure caused by cracks developing at certain solder points or on varistors on the circuit board. Owners report harsh or erratic automatic transmission shifting, stalling, no-start conditions, and check-engine lights because the ECM also controls transmission logic on these cars. Toyota conducted Safety Recall 10V384 to inspect and, if necessary, replace the ECM free of charge, making this one of the best-documented Corolla problems of the period.
Common Symptoms
- harsh 1-2 or 2-3 shifts
- delayed shifting
- check engine light
- no-start
- engine stalling
- transmission stuck in gear
- poor drivability
How to Fix
Diagnosis typically starts by confirming erratic shift behavior, communication issues, or stored transmission/engine codes, then verifying ECM part number applicability. The permanent fix is replacement of the ECM/PCM with the updated unit, followed by code clearing and confirmation of normal shift operation. Technicians should also inspect battery voltage and grounds so a weak electrical system is not mistaken for module failure.
Owner tips & cautions
- TipVerify the ECM part number and campaign applicability before buying a used module; many owners solved repeated shift issues only after installing the updated superseded ECM.
- TipCheck battery voltage, charging output, and grounds first, because low system voltage can mimic module and shift-solenoid faults.

Frequently asked questions
What does P0758 mean?
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). 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.
What are the most common causes of P0758?
The most common causes of P0758 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0758?
Repair costs for P0758 range from $200 to $5,000, depending on the vehicle and root cause.
