What the P0758 code means. Shift solenoid B allows the transmission to shift between second and third gear. If the PCM records code P0758, it indicates that the PCM cannot see the proper change in engine RPMs or the correct increase in road speed that should be happening during a shift from second to third gear.
What causes P0758?
When the code P0758 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing the specified rpm change that occurs during a shift from 2nd gear to 3rd gear. It’s also not seeing the correct increase in road speed from the vehicle speed sensor.
How do you fix a shift solenoid D stuck?
What Repairs Will Fix P0767?
- Changing the transmission fluid and filter.
- Replace faulty solenoid.
- Repair or replace a faulty transmission pump.
- Repair or replace defective transmission valve body.
- Perform transmission flush to clean passages.
- Cleaning corrosion from connectors.
- Repairing or replacing wiring.
How do you fix a shift solenoid B malfunction?
The most common repair for the P0755 code is replacement of the shift solenoid circuit.
However, other repairs may include:
- Replacing a failed shift solenoid.
- Topping off low fluid.
- Changing burned, dirty fluid.
- Replacing or repairing a damaged wiring harness.
Where is the transmission shift solenoid located?
Transmission Shift Solenoid Location
The Transmission shift solenoids are located inside the valve body of your automatic transmission. They are integrated into the valve body, and on some car models, you can see them without removing the valve body, while on others, you have to remove the valve body to reach them.
How much does a shift solenoid cost?
Shift Solenoid Repair and Replacement Cost
The overall cost to replace the shift solenoid in an automatic transmission ranges from $200 to $500 for a single solenoid. If the damage requires you to replace the entire solenoid pack the cost increases to between $250 and $700.
What does shift solenoid A and B do?
Shift solenoids open and close valves in the valve body to allow transmission fluid to reach your clutches and bands for a smooth shift. A malfunctioning shift solenoid “B” can potentially interrupt this process and cause a variety of transmission problems, which can make your vehicle undrivable.
What is shift solenoid D?
The shift solenoid D is part of the transmission system; it helps to manage the transfer of fluids between circuits, and to change transmission gear ratios. This solenoid is directed by the ECM, which monitors the solenoid’s voltage reading to ensure that it is working correctly.
What does code po700 mean?
The P0700 code indicates that there’s a malfunction with your vehicle’s Transmission Control Module (TCM). This computer monitors your transmission and works with the Powertrain Control Module (PCM) and Engine Control Module (ECM) to shift gears when necessary.
How do I fix error code P0766?
What repairs can fix the P0766 code?
- Replacing faulty shift solenoid.
- Clearing blocked transmission fluid passages.
- Repairing internal failures in the transmission.
- Refilling low, dirty, or contaminated transmission fluid.
- Replacing open or short shift solenoid D valve harness.
What does shift solenoid B stuck on mean?
Common reasons are: Hydraulic blockages happening inside the internal transmission fluid passages. Malfunctioning shift solenoid. Low transmission fluid. Transmission fluid that is dirty or otherwise contaminated.
What is a pressure control solenoid B?
Most automatic transmissions have three solenoid groups that are labeled as A, B, and C. The PCM controls these solenoids to direct fluid at the appropriate pressure to various hydraulic circuits. These pressure changes cause the transmission to change gear ratios at the correct timing.
