Is the Bora 1.4T transmission dry or wet?
1 Answers
The Bora 1.4T transmission is dry. A wet dual-clutch transmission must have a liquid pump, lubricating fluid, cooling pipes, and an external cooling system. The dry dual-clutch, by saving the related hydraulic systems, has advantages in manufacturing cost, weight reduction, and space structure optimization. Additionally, since the dry dual-clutch lacks hydraulic resistance, it offers higher transmission efficiency and better fuel economy compared to the wet type. Symptoms of clutch damage are as follows: 1. Clutch slipping: When starting the car in a low gear, after releasing the clutch pedal, the car either does not move or has difficulty starting; when accelerating, the speed does not increase with the engine RPM, leading to a feeling of weak driving, and in severe cases, phenomena like a burning smell or smoke may occur. 2. Incomplete clutch disengagement: Even when the clutch pedal is fully depressed, the power between the clutch's driving and driven discs is not completely cut off, resulting in difficulty shifting gears, gear grinding, or inability to stop, along with clutch overheating. 3. Clutch shudder: The entire car shakes when starting, especially at idle speed when gradually releasing the clutch pedal to start in a low gear, causing continuous jerking. 4. Abnormal clutch noise: When the clutch pedal is slightly depressed, as the inner end face of the release bearing just contacts the release lever, the clutch makes a continuous "click, click, click" sound; noise accompanied by shaking occurs when engaging at start-up or disengaging while driving.
