Disadvantages of the Getrag 6DCT451 gearbox

• A well-known weak point of a robotic transmission is the splined connection of the even-speed hub;
• If you drive too aggressively, the splines wear out, and the transmission goes into emergency mode;
• Other problems are related to clutch wear and contaminated solenoids;
• If oil leaks through the oil seal, clutch pack wear accelerates dramatically;
• The dual-mass flywheel has a short service life; it is sometimes replaced at 150,000 km.
