Key Features & Benefits

This little guy basically controls how the gearbox shifts between gears – drive, neutral, and reverse. It uses internal seals and valves to direct hydraulic fluid, and that fluid pressure is what actually moves the gears into place. It’s a pretty precise operation, making sure everything lines up correctly. Think of it as a key component in getting power from the engine to the wheels. When you move the shifter, that motion activates this cylinder. It doesn't do the shifting directly, it’s more like it tells the gearbox how to shift. It’s right in the heart of the transmission system.

Symptoms, Risks & Replacements

Without this working correctly, you won't be able to select gears reliably. You might get stuck in one, or it might slip out, or you might not be able to engage reverse at all. It acts like a shield protecting the gearbox from incorrect shifts. You’ll notice if this starts to go because your shifting will become rough, hesitant, or just plain impossible. A failing cylinder can also cause a lot of noise from the transmission. You can find a replacement at places like Fixparts Online, and honestly, getting a new one is a lot cheaper than rebuilding a whole gearbox.
