Technical FAQs
Q1: What is the primary function of this speed sensor on an Eaton Fuller transmission?
This sensor is a critical input device for the transmission control system. It precisely monitors the rotational speed of the transmission output shaft. This real-time speed data is essential for proper gear shifting, cruise control, and vehicle speed indication, ensuring optimal drivetrain performance and fuel efficiency.
Q2: Why is "High-Precision" so important for a transmission speed sensor?
High precision in the sensor's signal is crucial for the Transmission Control Unit (TCU) to make accurate and timely decisions. A clean, precise signal ensures smoother shifts, prevents gear hunting or harsh engagements, and provides reliable data for other vehicle systems.
Q3: How can I confirm PN: 4308074 is the correct sensor for my transmission?
This part number is engineered as a direct OEM replacement for specific Eaton Fuller transmission models. Verify that PN: 4308074 matches the original part number specified for your transmission model and serial number. Consult your transmission manual or a parts specialist for confirmation.
Q4: What makes this sensor reliable in harsh heavy-duty environments?
This sensor features a robust housing resistant to moisture, oil, and vibration. Internal components and magnetic elements are designed for long-term stability across wide temperature ranges, providing consistent signal output throughout commercial vehicle operation.
Q5: What are the consequences of a failing or inaccurate speed sensor?
A faulty sensor can cause: erratic or harsh shifting, inaccurate speedometer readings, loss of cruise control functionality, warning light illumination, and potential transmission limp-home mode activation.
