Is the Volkswagen Dry Dual Clutch Transmission Reliable Now?
1 Answers
The inherent flaw of poor heat dissipation in dry dual-clutch transmissions remains unchanged. If the driving conditions exceed its tolerance, it can still fail due to overheating. Here are the relevant details: 1. The high failure rate of dry dual-clutch transmissions is primarily due to their inadequate heat dissipation performance. In stop-and-go traffic conditions that require frequent gear shifts, the clutch remains in a semi-engaged state for prolonged periods. The two pressure plates generate heat through friction due to speed differences, and once a certain temperature threshold is reached, the transmission overheats, leading to a 'shutdown.' 2. The poor heat dissipation of dry dual-clutch transmissions is determined by their structural design, and there is no way to alter this fundamental characteristic. While heat dissipation cannot be improved, the heat output of the transmission can be reduced. 3. By upgrading the transmission control software, the vehicle's computer can delay shift timing and reduce the frequency of gear shifts, thereby minimizing the time the clutch spends in a semi-engaged state. This approach compensates for the dry dual-clutch's heat dissipation shortcomings by reducing heat generation.
