JCB equipment owners, if you're having transmission issues or warning lights, this oil pressure sensor switch might be what you need! This replacement part fits JCB backhoe loader models including 1400B, 1550B, 1600B, 1700B, 214, 215, 216, 217, 3C, 3CX, 3D, 3DX, 4C, 4CN, and 4CX. It replaces part numbers 701/41600, 701/37300, 701-41600, 701-37300, 70141600, and 70137300. The sensor monitors transmission oil pressure and sends signals to your machine's control system. When these sensors fail, you might get inaccurate pressure readings, warning lights, or transmission performance issues. The construction features stable characteristics and high reliability - this isn't some cheap knockoff that'll fail quickly. Installation is straightforward if you're familiar with basic mechanical work - usually just removing the old sensor and threading this one in place with proper sealing. The package includes just the sensor itself (no instructions, but the installation is typically simple). The color matches the photos, and the quality feels substantial. These sensors are crucial for proper transmission operation and protection, so using a quality replacement is important for preventing more serious (and expensive) transmission damage down the line. If your JCB is showing transmission pressure warnings or not shifting properly, this sensor replacement is often the first thing to check before diving into more complex transmission repairs. Keep your equipment running reliably with this direct replacement sensor that matches OEM specifications without the OEM price tag. Always double-check your specific machine model and existing part number before ordering to ensure perfect compatibility!
