It features mounting points using 4x Ø 9.0 mm bolts, and port connections of M14 x 1.5, M16 x 1.5, and a flap exhaust for port 31.

Key Features & Benefits

Basically, a servo clutch uses a small electric motor and some hydraulics to automatically engage and disengage the clutch for you. Instead of you manually pressing the clutch pedal, the system does it based on vehicle speed and other factors. It handles the clutch operation, making shifts smoother and easier. It controls clutch pressure, manages engagement speed, and generally takes over that part of the driving process. It’s usually found in vehicles with automated manual transmissions – so think of a manual gearbox but without the need for you to physically use a clutch pedal. It replaces the traditional cable or hydraulic linkage you'd find in a regular manual, and the computer controls it. It’s a key part of making those transmissions work properly.

Symptoms, Risks & Replacements

Well, it’s pretty vital to how the transmission operates. If it fails, you’ll likely notice issues with shifting – it might be jerky, the car might not shift at all, or you could even get stuck in gear. Because it’s computer – controlled, sometimes issues can trigger warning lights on your dash. It’s a bit of a complex component, so diagnosis can be tricky. If you’re looking to replace one, places like Fixparts Online usually carry a good range of options. It’s one of those things that when it’s working right, you don’t even think about it, but you’ll notice if it starts to go bad.
