The primary function of gear oil is to lubricate the moving parts within the transmission, including gears, bearings, and synchronizers. This lubrication reduces friction, which is essential for maintaining operational efficiency and preventing overheating. Excessive friction can lead to premature wear, reducing the lifespan of the transmission and leading to costly repairs. Moreover, gear oil also acts as a hydraulic fluid that enables the proper functioning of the gears during shifting.

The primary role of the transmission oil pressure switch is to monitor the hydraulic pressure of the transmission fluid. This fluid is vital for lubricating the various components within the transmission, allowing for smooth operation when changing gears. The oil pressure switch sends a signal to the vehicle’s onboard computer (ECU) to indicate whether the fluid pressure is within the required range.
