What are the causes of transmission failure in the 2012 New Focus?
1 Answers
Focus transmission failures include abnormal noises in neutral gear, abnormal noises in low-speed gears, reduction or elimination of sounds in high-speed gears, abnormal noises from various gears in the transmission, and noise from the transmission device. The relevant troubleshooting methods are as follows: If there is a metallic dry friction sound while driving and the transmission housing heats up, it is noise caused by deteriorated lubricating oil. It is necessary to add oil or check the oil quality and replace it if necessary. If there is abnormal noise in neutral gear and the sound disappears when the clutch pedal is pressed, it is usually caused by loose front or rear axle bearings or meshing gears. Any gear can produce noise, but if the rear bearing of the second shaft makes abnormal noises, it indicates severe looseness or damage to the bearing, requiring repair or replacement. When the vehicle is driving at low speeds, it may produce irregular noises. As the speed increases, more chaotic gear impact sounds and filtering sounds may occur. If the noise is slightly loud but the cutting force is relatively uniform, the vehicle can continue to be used after running-in. If the noise is severe or uneven, it should be disassembled for inspection and running-in, and adjustments or replacements should be made if necessary.
