Gearbox Shift Unit Flange Screw Position Sensor Replacement for Scania P420 P G R T Series Trucks | OEM 1527384

Product Overview The 1527384 Gearbox Shift Unit Flange Screw Sensor is a specialized, heavy-duty position-sensing bolt engineered as a premium aftermarket replacement for Scania commercial trucks and heavy transport tractor units. Integrating a high-sensitivity proximity switch inside a threaded structural bolt housing, this sensor mounts directly into the transmission flange assembly or the shifting cylinder housing. It accurately captures internal shifting rails and gear engagement movements, delivering immediate gear-state data to the transmission control unit (TCU). This eliminates shifting delays, erratic Opticruise automation behavior, and dashboard gear-display flickering. Technical Specifications Primary Scania OE Reference Code: 1527384, 1527384-Bolt Component Type: Transmission Shift Position Sensor / Flange Screw Inductive Switch Thread Profile: High-tensile, fluid-sealed specialized machine thread Application: Gearbox Shifting Cylinder & Selector Actuator Assembly Condition: Brand New Premium Aftermarket Replacement Vehicle & System Compatibility This flange screw position sensor features exact factory thread pitches and contact depths, providing seamless compatibility with Scania 4-Series, 5-Series (PRT range), and 6-Series global powertrain layouts: Vehicle Model & Series Gearbox & Transmission Application Scania P-Series (e.g., P420, P380, P400) Widespread use in regional distribution trucks and concrete mixers operating manual or automated Opticruise gearboxes. Scania R & G-Series Long-Haul Tractors (e.g., R420, G420, R470, R500) Fits heavy-duty fleet tractor units utilizing split/range multi-speed transmissions (GR875, GRS895, GRS905 series). Scania T-Series & Vocational Chassis Compatible with conventional bonneted rigs and heavy construction tippers requiring reinforced chassis electronics. Performance Benefits Flawless Gear Synchronization: Prevents missing gear faults, hard shifts, and random defaults to neutral caused by degraded internal inductive coils. Dual-Purpose Structural Design: Serves as both a high-tensile mounting flange bolt and a sealed electronic data sender, reducing component footprint on the transmission casing. Extreme Fluid & Pressure Sealing: Engineered with premium oil-resistant thread coatings and an O-ring shoulder to seal against pressurized gearbox oil and extreme temperature cycles. Maintenance Tip: In heavy-duty logistics operations, gear engagement failures or “Transmission Fault” dashboard alerts are often traced back to the 1527384 screw sensor being fouled by fine metal particles floating in old gearbox oil, or wire fatigue at the connector root. When installing this replacement bolt sensor, always clean out the threaded receiver port to prevent cross-threading. Use a calibrated torque wrench according to Scania workshop manuals to prevent overtightening the sensor body, and ensure the wire harness clip is snapped tightly to keep water splash and road dust out.
