P0757 CHEVROLET code

What the P0757 code means. Your vehicle’s computer-controlled transmission relies on shift solenoids to manage fluid transferring between hydraulic circuits to trigger a change in transmission to gear ratio. Code P0757 shows up when the PCM senses an abnormality during this process in solenoid B.

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:

  1. Replacing a failed shift solenoid.
  2. Topping off low fluid.
  3. Changing burned, dirty fluid.
  4. Replacing or repairing a damaged wiring harness.

Where is the shift solenoid valve 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.

What does shift solenoid B stuck on mean?

The shift solenoids are small on/off plunger type devices that control the flow of pressurized transmission fluid inside the valve body. Without them, the ATF would not flow through the proper channel to actuate a gear change.

What causes shift solenoid failure?

A transmission solenoid can fail due to electrical issues, or dirty fluid that’s caused the shift solenoid to become stuck open / closed.

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 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.
