A key component of the transmission system – this is a high-quality transmission oil pressure sensor (switch) by GX-AFTER. It is designed for JCB JS series wheeled excavators (e.g., JS130W, JS160W, JS200). Its function is to continuously monitor the oil pressure in the transmission (gearbox) system. It sends critical information to the operator or control module, ensuring accurate readings, aiding diagnostics, and protecting the gearbox from damage due to low oil pressure.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.
| Brand | Type / Series / Model |
|---|---|
| JCB | Wheeled Excavators (JS): JS130W, JS145W, JS150W, JS160W, JS175W, JS200W |
The list above is for reference. The 701/80335 sensor is used on many different JCB machines. Always verify the part number from your old unit.
Before replacing the sensor, ensure the machine is switched off and all hydraulic/transmission pressure is released. Transmission oil may be hot – use caution to avoid burns.
The transmission oil pressure sensor is a critical monitoring component. It ensures the correct operating pressure for clutch packs and gear lubrication. Its failure can lead to severe transmission damage.

No. This sensor (701/80335) is for the transmission (gearbox) system. The engine oil pressure sensor (e.g., 701/80327) is a completely different part with different operating parameters and often a different thread.
2. My machine has no drive. Will replacing this sensor fix it?It depends. If the machine won't drive and the transmission pressure light is on, a faulty sensor giving a false reading could be the cause. However, it could also be a genuine lack of pressure (e.g., low oil level or a failed transmission pump). Diagnosis is required first.
3. Will this fit a JCB 3CX backhoe?No, this sensor is specified for JS Wheeled and Tracked excavators. The 3CX/4CX backhoe loaders use different transmission pressure sensors, such as 701/80519.
