Q:

What is a shift solenoid C malfunction?

A:

When a shift solenoid C malfunctions, it causes a car's transmission to shift incorrectly, which makes it difficult or impossible to drive that car. The shift solenoid is a crucial part of the transmission, which reads computer signals from the powertrain control module (PCM). The PCM tells the solenoid to open and close its valves, allowing the flow of transmission fluid, essentially telling the transmission where to shift.

Problems that arise from a shift solenoid C malfunction include:

  • No downshifting: When driving at normal speeds and slowing down, the car will not shift into a lower gear, which causes a rough and slow acceleration.
  • No reverse: Reverse will seem to be nonexistent, the car will act as if it is in neutral, and the engine will run without the car moving.
  • Skipping gears: The vehicle will miss the appropriate gear or shift randomly when the vehicle is at a stop.

  • Q:

    What does a transmission control solenoid do?

    A:

    The transmission control solenoid communicates to a car when it is time to shift gears, if the car has an automatic transmission. If the shifting in the car's engine is balky or has other problems, the issue is likely an error with the control solenoid. Because a fairly sophisticated measurement of hydraulic pressure is necessary to operate the transmission, a solenoid that loses sensitivity to this factor is headed for repair or replacement.

    What is an automatic transmission solenoid?

    A:

    A transmission solenoid is an electrically operated valve present in automatic-transmission vehicles. The valve controls the flow of fluid in and throughout the automatic transmission.

  • Q:

    What will dirty transmission fluid do to a car?

    A:

    Dirty transmission fluid causes problems when shifting gears: grinding noises, stalling or misfiring of the engine and overheating of the transmission. These problems are very similar to those caused by low transmission fluid.

  • Q:

    What do shifting problems indicate in a car with an automatic transmission?

    A:

    Shifting problems in a car with an automatic transmission are an indicator of an issue with the transmission's internal or external components or of an electrical issue. Trouble shifting may indicate external controls that need adjustment or replacement, or it may signal that electrical components are not functioning correctly, according to AAMCO. It's also possible that shifting problems are caused by low or burnt transmission fluid, according to Mister Transmission.
