What is the lifespan of a dry dual-clutch transmission (DCT)?
1 Answers
The lifespan of a dry dual-clutch transmission (DCT) is typically three to five years. Here are some methods to extend the life of a dual-clutch transmission: Avoid prolonged low-speed driving: During traffic congestion, low-speed following keeps the clutch plates in a semi-engaged state, with frequent shifting between 1st and 2nd gears. This accelerates wear during the break-in period and reduces the transmission's lifespan. Therefore, in low-speed following situations, you can shift to S mode or manually select 1st gear to avoid excessive shifting between 1st and 2nd gears, which causes severe wear and overheating of the transmission. Use the N (Neutral) gear appropriately: When the transmission is in D (Drive) gear and the brake is pressed, it remains in a semi-engaged state, increasing wear on the clutch plates. In stop-and-go traffic, try to move and then stop intermittently rather than continuously holding D gear and braking, avoiding semi-engaged creeping. It is recommended that if the wait time exceeds one minute, shift to N gear and engage the handbrake. Avoid shifting too quickly: The shifting referred to here is not upshifting or downshifting during driving but switching between R (Reverse) and P (Park) gears using the gear lever. Shifting into R gear before the car has completely stopped or immediately shifting into P gear before the car has fully halted during reversing can cause severe gear impact, commonly known as gear grinding. A common issue with dual-clutch transmissions is that the gears are particularly prone to damage from such impacts.
