What Causes High Oil Pressure in a Car?
1 Answers
An overfill of manual transmission oil can lead to high oil pressure, which may cause oil seals to leak. Additionally, the excess oil can overflow through the vent hole, increasing internal gear resistance. Below are the extended consequences of overfilling manual transmission oil: 1. Clutch Damage: When the oil level exceeds the dipstick line and submerges the gears, starting the car requires the gears to overcome the oil resistance, resulting in power loss. 2. Reduced Transmission Efficiency: The primary functions of transmission oil are lubrication and cooling. The oil dissipates heat through the transmission housing and cooler. If overfilled, the gears encounter greater resistance, diminishing the transmission's cooling capability and power transfer efficiency. This forces the engine to consume more fuel, thereby reducing the vehicle's overall fuel efficiency.
