4 Transmission Solenoid Warning Signs

By Mister Transmission

If your automatic transmission is performing erratically, it could be a sign your transmission’s solenoids are failing or have failed

Transmission solenoids are one of your automatic transmission’s many critical components.

Solenoids are electro-hydraulic valves. They control the flow of transmission fluid throughout the transmission, and they open and close as per the electrical signals they receive from your vehicle’s engine or transmission control unit, which pulls its data from a series of speed sensors in the engine.

Whereas a clutch controls how and when gears shift in a manual transmission, solenoids are part of an automatic transmission’s complex hydraulic system that performs the same task. Furthermore, there are various kinds of solenoids, including the transmission shift solenoid, the lockup solenoid, and the transmission control solenoid.

There are a variety of reasons as to why one or more of your transmission’s solenoids can fail. When your engine or transmission control unit sends signals to the solenoids to shift up or down, these valves open or close to allow or restrict the flow of transmission fluid. It’s the fluid that pressurizes your transmission’s clutches and bands and allows it to change gears.

What to Do When Transmission Solenoid Troubles Arise

Like any mechanical device or component, transmission solenoids do wear out with time. Standard preventative maintenance for your transmission can help offset their deterioration to a degree.

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

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

Depending on the make, model, and year of your vehicle, transmission solenoid replacement costs can vary. In general, a single faulty transmission solenoid replacement costs approximately $250. Replacing the entire solenoid pack can cost around $400.

Samantha Prowse
Always above and beyond!Mostly my car has gone in for basic maintenance, but recently I had a hitch installed on my car. In the process of having this done it was noticed I had a sensor malfunctioning. NO PRESSURE what so ever to have this fixed at the same time. I was told the risks and given a choice. I chose to fix it as my car was in anyway, but I loved having the choice with no judgement or pressure. Pricing was fair, and definitely less than I was expecting. I didn't feel my lack of car knowledge as a female was an issue here at all. I was made to feel informed and involved. I recommend this shop to all of my friends ☺️
