How do I fix code P0758?

How do I fix code P0758?

What repairs can fix the P0758 code?

1. Replacing a faulty shift solenoid.
2. Replacing a defective valve body.
3. Repairing or replacing damaged wiring or connectors.
4. Adding more transmission fluid or changing out contaminated transmission fluid.

What code is 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.

What is a shift timing solenoid?

The transmission control module, or TCM, uses data from the shift/timing solenoids to manage hydraulic fluid transfers between circuits, and to perform changes in transmission gear ratios in order to accelerate, decelerate, optimize fuel efficiency, and maximize engine performance.

Where is shift solenoid B located?

The shift solenoid is located inside the oil valve connected to the valve body. The shift solenoid controls gear engagement and gear shift. The engine control module or the transmission control module in the vehicle’s engine controls the shift solenoid electronically.

How do you diagnose a bad transmission solenoid?

If you’re experiencing transmission solenoid troubles, it will become evident in one of four ways:

1. Delayed gear shifting.
2. You can’t downshift, and your engine continues to rev even when applying the brakes.
3. Your transmission gets stuck in neutral.
4. Shifting gears become rough and choppy.

What is a shift solenoid B?

Shift solenoid B enables the transmission to shift from 2nd gear to 3rd gear. It does this by re-directing the flow of the transmission fluid which changes the position of the shift valves in the valve body.

How much is a torque converter clutch solenoid?

The individual solenoids only cost $15-$30, on average, but can be as much as $100. Labor can range from $70-$150, depending on how many solenoids you need to have replaced and how long it takes to replace each one, based on the kind of car you have.

What does trouble code p0758 mean on a Chevy?

Troubleshooting and solving a trouble code P0758 usually involves replacing the 2-3 shift solenoid. Before buying and replacing the shift solenoid, I recommend that you test it to make sure its bad. Testing the solenoid’s internal resistance (specification: 19-31 Ohms). Checking its electrical connector for damage.

What causes Shift Solenoid B to record a p0758 code?

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 the P0758 code? A number of issues can cause the PCM to record a P0758 code, including: Shift solenoid B is faulty.

What causes a PCM to record a p0758 code?

A number of issues can cause the PCM to record a P0758 code, including: Shift solenoid B is faulty. The wiring or connector for shift solenoid B is loose, shorted, or open. The valve body is defective. The transmission fluid is low and/or contaminated. What are the symptoms of the P0758 code?
