Dual-Clutch Gearbox Fluid and Seal Leaks
SeriousGearbox & TransmissionThe Getrag 7DCL750 dual-clutch transmission can develop oil leaks from the main shaft seals, leading to fluid loss, pressure drops, and degraded shift quality. Early 2010–2011 models are particularly susceptible to seal deterioration from heat cycling in the transmission tunnel. Skipping the recommended transmission fluid service interval accelerates wear on the clutch packs and valve body.
